Changes from R8.1 to R9
-----------------------

The following changes have been made to Sega
Dreamcast SDK Release 9:

Audio64
-------

The audio64 driver contains three important fixes:

- On certain Sega Dreamcast units bad modem
  connections would result in the generation of
  spurious MIDI interrupts.  This caused the
  driver to fail.  Spurious MIDI interrupts are
  now properly rejected by the driver.
   
- There was a timing problem that caused the
  contents of AICA registers to become corrupt in
  certain situations. This has been fixed.

- Pitch shifting was broken. Subtle changes would create
  larger jumps. This has been fixed. acDigiSetCurrentPitch
  now works properly.
 
   
The amSoundStop() routine will now positively stop
the sound given it via retrying the acDigiStop()
command with a slight pause. This ensures that
looping sounds are stopped on the first try every
time.

KTBOOL amSoundReleaseVoiceChannel(AM_SOUND_PTR theSound)

This allows the app to release a voice channel
that was allocated to a sound that will not be
played. If a sound is not played and a voice was
allocated it will be lost permanently if it is not
released.

KTBOOL acIntSetMessagingMode(AC_MESSAGE_MODE
       messageMode)

Now the message handler (ARM interrupt handler)
can either be attached to the ARM interrupt
(async) or to the VBLANK interrupt (isync). If no
messages have been sent by the driver the routine
will return and do nothing.

void acIntSetPollingRate(KTU32 pollingRate)

This allows the polling rate of the vblank based
message handler to be adjusted.

KTBOOL acDigiGetCurrentReadPosition(volatile KTU32
voiceChannel,volatile KTU32 *currentSampleFrame)

Gets the current read position of the PCM play
cursor in frames from the start of the buffer.

void acG2FifoCheck (void);

Checks the Holly and AICA FIFO's and returns when
the FIFO's are clear.

KTBOOL acG2Fill( volatile KTU32 *target,KTU8
       value,KTU32 sizeInBytes);

Fills an area of G2 memory, a G2 compliant version
of memset()

KTBOOL acG2Read (volatile KTU32 *target,volatile
       KTU32 *source,KTU32 sizeInBytes);

KTBOOL acG2Write (volatile KTU32 *target,volatile
       KTU32 *source,KTU32 sizeInBytes);

Read or Write to G2 memory from SH4 memory.

KTBOOL acG2ReadLong (volatile KTU32 *address,KTU32
       *value);

KTBOOL acG2WriteLong (volatile KTU32
       *address,KTU32 value);

Read and write longs to G2 memory. The read does a
double read to insure that accurate values are
delivered back.

KTBOOL acDmaInstallHandler (AC_DMA_TRANSFER_PROC
theTransferProc);

Allows installation of a DMA handler, see MyDma.c

KTBOOL acDmaInit (void);
KTBOOL acDmaShutdown (void);

Called by the AM layer to init and de-init the DMA shell.

KTBOOL acDmaSuspendAll         (void);
KTBOOL acDmaResumeAll         (void);

Suspend and resume all DMA calls for the G2 layer.

- Boilerplate changes

*** MySfx.c

MyLoadBank() now allocates a temp buffer in SH4
memory as direct reads to AICA memory are not
supported by the GDFS API.

MyPlaySoundEffect() & MyPlaySoundEffectFX()

Now demonstrate the use of
amSoundReleaseVoiceChannel() post voice allocation
to free the voice on error exit from the function.

*** MyStream.c

This has been updated to manage its own instance
memory pool.

*** MyInt.c

This has been updated to show the current
ARM/VBLANK interrupt handler and callback handler.
This is not invoked by the sample code but the
handlers invoked are the same as these.

*** MyAmSetup.c

This is a new module that contains the setup code
for the AM library. It allows via a boolean
argument the selection of ARM or VBLANK interrupt
driven messaging.

*** MyDma.c

This contains the monolithic DMA shell proc that
is installed into the audio system to provide
SuspendAll and ResumeAll functionality.


Movie / Middleware
------------------

- Sample added to support movie playback with Kamui2.
  MPEG movie playback and Kamui2 will now work together.
  See sample: \Sample\Movie\mw_km2

- Audio64.drv updated for Duck samples.


GNU C/C++
---------

- GCC updated to Phase 2, Final 33, ELF.

- Fixes C++ debugging. Previously debugging
  class structures through Codescape was broken. This is
  now fixed.


Flash Utility
---------------

- Updated GDRFlash bios to version 0.52


Codescape
---------

- Updated to version 145

- Fixes the follwing bugs:

1)  If a large file (~16Meg) that contains no
    linefeeds or carriage returns is dropped on
    to CodeScape, the debugger appears to stop.

2)  In the Call Stack when the address is offset
    from a label it sometimes looks to chose the
    wrong label to offset from. The offset is still
    a correct / valid expression but it looks wrong.

3)  If in the breakpoint configure dialog an invalid
    expression is entered and OK is hit. The dialog
    warns that the expression is invalid (this is
    correct), but it then disables the breakpoint
    and closes the dialog.

4)  The Advanced breakpoint options are not greyed out
    when the breakpoint type is set to software.



Changes from R8 to R8.1 Update
------------------------------

The following changes have been made to Sega
Dreamcast SDK Release 8:

Shinobi
-------

- Shinobi.lib updated to version 1.44.

- Fixed a serious bug in the syCache module which directly
  affects movie playback.  The symptoms of the bug were:

  1. Movie player may enter an infinite loop when a movie
     is started.
  2. Joypad input may be lost during the playback of a movie
     and never return.
  3. A GD-ROM read may fail and all subsequent reads fail.

- Profiler.lib updated to match Shinobi.lib version 1.44.

Audio64
-------

- Audio64.drv driver updated to version 1.80c.1.
  Minor change to interrupt layer to enable host IntID writeback.

- Audio64.lib matched to driver version 1.80c.1.
 
- Fixed a significant bug related to the shutdown and
  re-initialization of audio drivers during playback of MPEG movies.
 
  The bug was discovered under the following conditions:

  1. Application is loaded from a hard reset.
  2. Audio64 driver is initialized.
  3. Sounds are played via Audio64.
  4. Audio64 is shutdown.
  5. Manatee is initialized.
  6. Occasionally, sdMultiUnitDownload() locks up
     immediately after initialization in a call to
     G2AicaFifoWaitEmpty().
  7. Otherwise, the first frame of the movie may
     play and then freeze.
  8. Exiting out of the movie player at this point may
     cause subsequent calls to Audio64 initialization to
     fail with a driver mismatch error.

  The cause of the error was the DSP running freely during the
  period between shutdown and startup of audio drivers.  Under
  certain conditions, the DSP would overwrite sound memory.
  The fix to the Audio64 library is to clear the DSP during
  startup and shutdown.

- Audio64.lib modified for G2-bus compliency.

- Support added for Store Queue writes to sound memory to improve
  the performance of audio sample loads.

- Audio64 header files [ac.h, am.h] modified to support changes
  to driver and library.

  Added acSystemClearDspRegisters()

  Moved acSystemGetCurrentReadAddress() functionality to
  acDigiGetCurrentReadPosition()

  Added error check for AC_NON_32_BYTE_ALIGNED_SIZE

  Chainable ARM interrupt handler exposed

- All audio sample programs updated to match new driver and library
  versions 1.80c.1.  [Assets did not change].

Kamui
-----

- Ninja.lib updated with Kamui version 1.10.0.1 (Jul 09, 1999 build).

- Support added for 512 line PAL video modes.

  Kamui's standard PAL support is for a 640x480 display letterboxed.
  With the new 640x480EXT video modes, the display can be stretched
  to cover 512 lines and greater.

- Kamui header files [kmapi.h kmstruct.h kmenum.h] changed:

  Added kmSetPALEXTCallback()

  typedef struct _tagKMPALEXTINFO
  {
      IN    KMDISPLAYMODE   nDisplayMode;
      OUT   KMINT32         nPALExtMode;
  } KMPALEXTINFO,*PKMPALEXTINFO;
 
- New video modes:

  KM_DSPMODE_PALNI640x240EXT
  KM_DSPMODE_PALNI640x480EXT
  KM_DSPMODE_PALI640x480EXT

  typedef enum
  {
      KM_PALEXT_HEIGHT_RATIO_1_033 = 0,  /* 247 || 495 */
      KM_PALEXT_HEIGHT_RATIO_1_066 = 1,  /* 255 || 511 */
      KM_PALEXT_HEIGHT_RATIO_1_100 = 2,  /* 263 || 527 */
      KM_PALEXT_HEIGHT_RATIO_1_133 = 3,  /* 271 || 543 */
      KM_PALEXT_HEIGHT_RATIO_1_166 = 4,  /* 279 || 559 */
  } KMPALEXTHEIGHT;

Kamui2
------

- Kamui2.lib updated to version 16.3.2.4 (Jul 23, 1999 build).

- Support added for 512 line PAL video modes.

  Kamui2's standard PAL support is for a 640x480 display letterboxed.
  With the new 640x480EXT video modes, the display can be stretched
  to cover 512 lines and greater.

- Kamui2 header files [km2api_clb.h km2strct.h km2enum.h] changed:

  Added kmSetPALEXTCallback()

  typedef struct _tagKMPALEXTINFO
  {
      IN    KMDISPLAYMODE   nDisplayMode;
      OUT   KMINT32         nPALExtMode;
  } KMPALEXTINFO,*PKMPALEXTINFO;
 
- New video modes:

  KM_DSPMODE_PALNI640x240EXT
  KM_DSPMODE_PALNI640x480EXT
  KM_DSPMODE_PALNI640x480FFEXT
  KM_DSPMODE_PALI640x480EXT

  typedef enum
  {
      KM_PALEXT_HEIGHT_RATIO_1_033 = 0,  /* 247 || 495 */
      KM_PALEXT_HEIGHT_RATIO_1_066 = 1,  /* 255 || 511 */
      KM_PALEXT_HEIGHT_RATIO_1_100 = 2,  /* 263 || 527 */
      KM_PALEXT_HEIGHT_RATIO_1_133 = 3,  /* 271 || 543 */
      KM_PALEXT_HEIGHT_RATIO_1_166 = 4,  /* 279 || 559 */
  } KMPALEXTHEIGHT;

- Kamui2_d.lib updated to match Kamui2.lib version 16.3.2.4.

- Km2util.lib and Km2utl_d.lib updated to match Kamui2.lib
  version 16.3.2.4.

- Minor change made to the makefile for QuikTst2 to pass the correct
  graphics API (KAMUI2).

Movie / Middleware
------------------

- Mw_snd64 sample updated to reflect changes in Audio64 library.

- Audio64.drv updated to version 1.80c.1 for Duck samples.

- Official logo images added for MPEG Sofdec, ADX, and Truemotion
  movie and streaming formats.  See the Sega publishing standards for
  proper usage.  Images provided in ".bmp" format in 640x480 and
  320x240 resolution with black or white backgrounds.

- MPEG Sofdec movie encoders [both plug-in and stand-alone tools]
  updated to version 1.02.

  Fixes several crashing bugs
  RGB-YUV converter optimized
  Multiplexer sped up

- Minor update to ADX encoder.  Switched from debug version to retail.

Codescape
---------

- Updated CodeScape to version 2.2.0 Build 137.

- Fixed the following bugs:

  Active overlay was ignored in label and symbol lookup.

  When the user correctly calls MWNotifyOverlayLoaded. CodeScape
  did not recognize that an overlay had been loaded.

  Shortcuts in Overlay Management Dialog did not operate correctly.

  Construction of abbreviated filenames produced extensive load times.

GD Workshop
-----------

- Updated GD Workshop to version 2.7.0f.

- Important bug fix to "Save CRI script" feature.

  The version of GD Workshop that shipped on R8 had a problem keeping the
  correct order of tracks and files after items were deleted or added
  to a project.  This update correctly exports CRI ".scr" files for use
  with CD Craft.

IP Maker
-------

- Updated IP Maker to version 1.0.3.0.

- This version now allows U.S. and European product ID's to be entered
  into the appropriate field instead of through the "Free Entry" box.

- A registry file is provided to set the IP Maker tool to default settings,
  including English text.  Double-click on this file to install it.

GNU C/C++
---------

- GCC updated to Phase 2, Final 29, ELF.

- Important fix for delayed branch bug.

- Fixed an "unrecognizable insn" bug in the compiler, and a related
  assembler/disassembler bug.

- Fixed a few incorrect opcodes.  These mainly affected debugger specific
  code (instructions using the SGR and DBR registers).  Also fixed some
  16-bit instructions (mulu.w/muls.w were specified as mulu and muls).


Changes from R7 to R8
---------------------

This is a list of some important changes between the previous Katana
development environment (R7) and this one.

- Support for the gnu compiler and linker was added.  All 220 sample
  programs in this release have been demonstrated to compile, link
  and run under the Hitachi, Metrowerks, and gnu compilers.  Developers
  wishing to use gcc as their primary compiler should read the file
  gcc.faq, located in the \utl\dev\gnu\readme directory.

- Initial Kamui2 support was added.  Kamui2 is an improved, low-level
  graphics API that provides developers fine-grained control over
  rendering states.  It also allows developers to manage texture
  memory themselves.

  However, Kamui2 is relatively new, and backwards compatibility
  between original Kamui applications and Kamui2 is not assured.
  Therefore, we are simultaneously supporting Kamui and Kamui2 in this
  release.

  Our quality assurance department was unable to fact-check the
  documentation for Kamui2 in time for general release, and so we
  provide it here in its original format in the \doc\Kamui2 directory.

- The new ginsu library was added.  Ginsu is an interface that allows
  for easy creation of sampler-type titles, for use in kiosks or
  demonstration versions of software.  Ginsu allows developers to
  create limited-functionality versions of their titles and allow them
  to be integrated gracefully onto a GD with titles from other
  developers.  It can also be used as a general purpose menuing
  system.  For more information, see doc\PDFs\Ginsu.pdf .

- The video streaming playback samples were updated to demonstrate how
  to do video playback using the Duck and CRI MPEG codecs, across the
  Audio64 and Shinobi audio libraries, in conjunction with all three
  compilers.  Each permutation of the listed tools and libraries is
  possible with R8.

- Install.txt (GetStart.pdf) was rewritten to correspond to the new
  processes for burning GD-ROMs.  Please review this document when
  creating a disc image for submission to Sega, as the burning process
  can be subtle.

- The DBFlash utility was updated to version 1.11, which includes some
  user interface improvements.  DBFlash is used to update the
  development hardware to the last versions of firmware.

- New CRI-compatible MPEG compressors were added.  This release
  includes the MPEG video compressor from Panasonic Wondertainment,
  and an MPEG export plugin for Adobe Premiere.

- Fifteen sample programs were included to demonstrate how to program
  the Visual Memory Unit, or VMU, as a separate development
  environment.

- sbinit.c was updated to work around a compiler bug where a
  semaphore is not correctly handled in the P2 area:

       _mp_SemaphoreAddress |= 0xA0000000;

- A submittable version of warning.da was added.  Developers will use
  this sound file in track 2 (CDDA) to warn people that the disc should
  not be played on standard CD players.

- Previous versions of the memcpy() function supplied in the Hitachi
  libraries failed to copy aligned structures of 256 bytes correctly.
  This has been fixed.

- Shinobi header files were wrapped with #ifdef __cplusplus blocks to
  work correctly with the gcc compiler.

- The audio control layer AC_CMD_PORT_PLAY_WITH_PARAMS command, was
  added to ac.h.  In addition, the following functions were added to
  the ac layer:

  acDigiPlay (KTU32 port,KTU32 startOffset, KTS16 aicaLoopFlag)
 
  acDigiPlayWithParameters (KTU32 port,KTU8 volume, KTU8 pan,
              KTU8 dspMixerChannel, KTU8 dspSendLevel, KTU32
              eventRequestAddress, KTU16 loopStartAddress, KTU16
              loopEndAddress)
 
  acDigiPlayWithLoopParameters (KTU32 port,KTU32 startOffset,
              KTS32 aicaLoopFlag,KTU16 loopStartAddress,KTU16
              loopEndAddress)

- Functions were added to the am layer to support MIDI playback.
  However, most of these functions are stubbed at this time.  If you
  require MIDI support for your title, please contact us at
  dts@sega.com .

- Metrowerks support of iostreams has been totally overhauled. 

- The parameters of the kdInitSystem() function were reversed:

  kdInitSystem(void* recvbuf, void* sendbuf);

- The following functions were added to kaede.h to support the
  development of lower-cost lightguns:

  void kdSetGunTrigger(Uint32 port);
  void kdSetGunCallback(Sint32 (*func)(void));
  void kdSetHandler(Uint32 num, void (*func)(void));

- Across all sample programs, sbinit.c was modified to support the gcc
  code startup conventions.

- Some new sample programs (CheapBump and Dragonfly) have been added to
  the kmDemo folder, courtesy of VideoLogic.

- The new Kamui initialization function, kmInitDevice(), is supported.
  New code should use this function, as it is more flexible.

- The following function was added to sg_sycfg.h:

  Sint32 syCfgGetDefaultLanguage( Sint32* ) ;

- The following function was changed in sg_sd.h:

  EXTERN SDE_ERR sdDrvGetErr( Uint32 *err);

- More comments were added to sg_pdvib.h to describe the use of the
  force feedback functionality (vibration unit) of Dreamcast.  Additionally,
  the comments in sg_pad.h were cleaned up.

- A macro, MWD_PLY_LATENCY, was added to mw_sfd.h to support the 2V
  versus 3V latency modes for Kamui playback.

- A new CellSprite data format was added to Ninja in the njdef.h section
  to support streaming of video surfaces into layered sprites.

- Support for several new VGA display modes was added to Ninja:

  320x240 VGA
  320x480 VGA
  640x240 VGA
 
  Flicker filtering is optional for each mode.

- The njDrawPolygon3DEx() series of functions was added to ninjaapi.h.
  This series of functions permits buffering and batch rendering of
  simple 3D primitives.

Changes from R6 to R7
---------------------

- C++ support was added, in the form of the Metrowerks CodeWarrior
  compiler and IDE environment.  Full documentation is supplied in PDF
  format.  Most sample programs in this release have been demonstrated
  to cross compile within the Metrowerks environment; for your
  convenience, CodeWarrior projects have been added to most sample
  programs.

- The process for building Shinobi programs was redesigned.  Microsoft
  Visual Studio is no longer required in order to build or run the
  sample programs included in this release.  Instead, the build
  process is designed around the freely redistributable gnu make
  (gmake.exe) utility for Win32.  Source code for the utility is
  included for your convenience.

- Set 5.23 development hardware support was removed from this release.
  You can check the version of development hardware you're using by
  looking at the first four characters of the serial number of the
  unit, located on the bottom of the development system.  If you are
  still developing using Set 5.23, please contact your account manager
  for an upgrade.

- The firmware for the Set 5.24 system was updated.  Your development
  system should be reflashed with the images included in this release:

    Debug adapter firmware (genie.fsh): 4.6.0a
    GD-M firmware (gm2_6_0h.fsh): 2.6.0h
    Boot ROM firmware (btrf5001.bin): 1.001

  This process happens automatically if a Set 5.24 system is connected
  to your development PC when you install R7.  The DBFlash utility is
  used to do this reflash, but DACheck can be used to reflash and
  check the debug adapter and GD-M.  For more information, see the
  \utl\dev\dbflash folder.

- Thirteen sample programs that demonstrate how to program the Visual
  Memory Unit (VMU) were added to the release, in
  \utl\dev\vmstools\sample.  These programs have not been tested and
  are provided for reference only.

- Movie compression and playback support was added to the release.
  Fifteen sample programs demonstrating the CRI MPEG and TrueMotion
  Duck codecs have been added to the \sample\movie folder, and
  compressors have been added to the \utl\gfx\conv\movie folder.

- There are now over 170 sample programs in this release.  Of
  particular interest is ScrnGrab, which demonstrates how to capture
  the current video frame and save it to the filesystem.  Useful for
  creating screenshots for magazines.

- CD Craft was added to the release, in the \utl\dev\cdcraft folder.
  It is expected that this command-line tool will assist developers in
  burning GD-ROMs for testing purposes.  CD Craft does not require
  that a Set 5.24 system be attached to the SCSI bus in order to burn
  a GD-ROM.

  This tool was a late addition to the release.  If you do not need to
  set up a separate station for burning GD-ROM images, please continue
  to use GD Workshop for this purpose.

- The documentation was overhauled.  Information was added and video
  play, targeting Dreamcast, the Metrowerks IDE, the Ginsu programming
  library, Codescape scripting, and getting started with Dreamcast.

- Newly developed, detailed technical presentations were added to
  \doc\training.  Information is also included about developing using
  Microsoft's Windows CE for Dreamcast (available separately).  For
  your convenience, PowerPoint and Word viewer programs were added to
  \doc\training\viewers .

- The new Audio64 library was added.  This is a new driver interface
  for allowing developers to play 64 sound samples simultaneously
  using the AICA engine.  There are two APIs for this interface,
  implemented in ac.h and am.h.  This library does not require the use
  of Macintosh tools in order to generate sound content.  To support
  the Audio64 library, five command-line tools for processing audio
  were added to \utl\snd\pc.  Additionally, two sample programs
  showing how to use the new interface were added to \sample\audio64.

- The release directory structure was overhauled to move most commonly
  used items nearer to the root of the release.

- The IPMaker utility was added into \utl\dev\ipmaker .  This utility
  allows you to generate IP.BIN files, which are required for disc
  verification, security, and testing.

- The method for checking for the output type -- VGA, NTSC or PAL --
  was redesigned.  The sg_sycbl.h file was updated, and the
  syCblCheck() function is now available for this purpose.

- Scripting support was added to GD Workshop and Codescape, via the
  Windows Scripting Host.  If you have not added scripting capability
  to your development PC, we have provided the self-extracting
  executables for this support in \utl\dev\scripting .

- The Hitachi linker automatically aligns certain data types that the
  Metrowerks compiler does not necessarily need to align.  Due to the
  fact that some Shinobi libraries (such as Kamui) expect their data
  types to be naturally aligned, the following bit of code was added
  to samples to force the Metrowerks linker to make them work:

    #ifdef  __MWERKS__
    #pragma align (4);
    #endif

  Kamui structures that previously happened to be allocated naturally
  at 32-byte aligned addresses should be forced to allocate at 32-byte
  addresses, if the CodeWarrior compiler is being used.  For an example
  of this, see the QTDirect sample program.

- Most sample programs rely on sbinit.c in order to initialize the
  filesystem.  This initialization previously failed if the filesystem
  for some reason became unavailable (for example, when a user removes
  the disc).  As a result, sbinit.c has been updated in all sample
  programs to poll the filesystem initialization function gdFsInit(),
  and if the filesystem does not respond after 8 tries, the program
  exits gracefully.  All shipping Dreamcast programs must behave
  similarly.

- The teapot and f40 sample programs were updated to demonstrate the
  correct way to check for the presence of a VGA versus NTSC displays.
  Additionally, QuikTest was updated to support PAL displays.

- The 3DS2Kamui tool, kindly supplied by VideoLogic, supports several
  new features.  Mesh animation, camera animation, UV transformations
  from materials, smoothing groups, texture export, online help, and
  #defines to indicate that a structure has been exported, have all
  been added to the tool.

  Normals are now renormalized before export, a bug in names export
  was fixed, and mesh export was rewritten to be more robust.

  Known limitations of the plugin include the following.  Exported
  materials only include the names of all textures, diffuse, specular
  and ambient colors, shininess, shininess strength, opacity, and
  shading type.  Animation doesn't support mesh morphing.  Face
  mapping (a special type of UV mapping) is not supported.  Textures
  are exported as RGB 24 bit bitmaps only.  The camera does not export
  ROL info.  Fans are not supported by the stripping algorithm.

- A .pvr texture exporter from Photoshop was added to
  \utl\gfx\phtoshop .

- Shinobi include files were #ifdef'ed to prevent accidental recursive
  inclusion.

- The bool type, defined in sg_xpt.h, was redefined to Bool, which is
  in turn #define'd to Sint32.  Note that CodeWarrior defines the type
  bool (lowercase b) to have a sizeof 1, and Hitachi C defines the type
  bool to have a sizeof 4.

- The libcross library for debug output was slightly modified so that
  most I/O functions, such as _write(), have been prefixed with
  _debug, e.g. _debug_write().  This is to avoid name conflicts with
  developer libraries.  See the memtest sample program for an example.

- The ld_ext() function now generates a warning if the type passed
  in is not (void *).

- Return values of the pdGetPeripheral() function are now cast to
  (PDS_PERIPHERAL *) to avoid compiler warnings.

- It's now possible for the application program to detect the
  country code of the target Dreamcast system.  The following
  functions were added to sg_sycfg.h:
 
    syCfgGetCountryCode  ( Sint32* ) ;
    syCfgGetCountryCode  ( Sint32* ) ;
    syCfgGetLanguage     ( Sint32* ) ;
    syCfgGetBroadcastType( Sint32* ) ;
    syCfgGetShortIndividualID( Sint8* ) ;
    syCfgGetIndividualID( Sint8* ) ;

- The following types were added to sg_pad.h:

    #define PDD_DEVTYPE_LIGHTGUN     (1 << 7)
    #define PDD_DEVTYPE_VIBRATION    (1 << 8)

- A function was added, gdFsIsTrayOpen(), to allow your application to
  check whether the GD-ROM tray has been opened by the user.

- Several functions were deleted from the gdfs interface.
  gdFsLoadDirFast(), gdFsChangeDirFast(), and gdFsOpenFast() are no
  longer supported.

- The Hitachi C compiler was updated.  Of particular importance are
  the following fixes:

  - A memory overflow error that occurred with very large arrays of
    literal values was fixed.

  - The compiler emitted illegal opcodes when the argument to some
    builtin functions additionally made a register store.  This has
    been fixed.

  - The preprocessor choked on some complex typed expressions such as
    (char *) cp = &(*char *)0xb804000).  This has been fixed.

  - Several optimization improvements have been added which can map
    structures into registers.

  - Literal character strings can now be 32767 characters long.

  - The compiler can align data types to 32 bytes.  Use
    #pragma aligndata32 to force this.

  - C++-style comments, //, are now supported.

  - By default, the compiler now no longer spews a copyright message
    on startup.
 
  - Floating point constants (such as 1.0f) can now be placed into a
    literal pool for use by assembly functions.  Previously, the
    preprocessor did not handle floats correctly.

- The following functions were added to Ninja:

   void njRenderStart( void );
   void njFlipFrameBuffer( void );
   void njSetEORCallBackFunction( void (*func)(void) );
   void njGetSystemInfo(NJS_SYSTEMINFO *info);
   void njMemCopy8( void *dst, const void *src, Sint32 num );
   void njMemCopy16( void *dst, const void *src, Sint32 num );
   void njMemCopy32( void *dst, const void *src, Sint32 num );
   void njMemCopySQ( void *dst, const void *src, Sint32 num );
   Sint32 njReLoadTexturePartNum(Uint32 n,Sint8 *addr,Uint32 offset,
     Uint32 size);
   Sint32 njReLoadTexturePartNumG(Uint32 globalIndex,Sint8 *addr,
     Uint32 offset,Uint32 size);
   Sint32 njLoadTextureReqStop(void);
   void njGarbageTexture(NJS_TEXMEMLIST *addr,Uint32 n);
   Sint32 njReadTextureNum(Uint32 n,Sint8 *addr);
   Sint32 njReadTextureNumG(Uint32 globalIndex,Sint8 *addr);
   Uint32 njCalcTextureSize(Uint32 nWidth,Uint32 nHeight,
     Uint32 nTextureType);
   void njSetTextureParam(NJS_TEXMEMLIST *texmemlist);
   void njCameraMotionOld(NJS_CAMERA *camera, NJS_MOTION *motion,
   Float frame );
   void njCameraActionOld(NJS_CACTION *caction, Float frame );
   Uint32 njGetPaletteMode(void);
   void njGetPaletteData(Sint32 offset,Sint32 count,void* data);
   Sint32 njReLoadTexturePartNum(Uint32 n,Sint8 *addr,Uint32 offset,
     Uint32 size);
   Sint32 njReLoadTexturePartNumG(Uint32 globalIndex,Sint8 *addr,
     Uint32 offset,Uint32 size);

- Nindows now supports the use of a Maple bus mouse.  See nindows.h.

- Several keywords were removed from the Ninja file format, and the
  3-D model exporters were updated to reflect this fact.  As a result,
  the following Ninja samples were removed from this release:

    Logo
    Temjin
    Motlink
    Simple

  Ninja models created with older versions of art tools will need to
  be re-exported in order to work correctly with R7.  (Files with an
  .nja and .nam extension created with R6 will not work with R7.)

- Kanji characters were cleaned out of a few of the sample programs.

- Shinobi header files had an #ifdef'd extern "C" declaration added to
  support compilation by CodeWarrior.

- Codescape, GD Workshop, and DACheck were all updated.  Check the release
  notes accompanying each tool for details.

Changes from R5 to R6
---------------------

- A first version of a 3D Studio Max R2 to Kamui converter was added
  to the \utl\gfx\conv\pc\3ds2kamui directory.  Special thanks to
  Videologic for supplying this early version.

- Macintosh-based sound conversion, layout and processing tools were
  added to the \utl\snd\mac directory.  The Macintosh archive in this
  directory contains four programs for use with the Katana Sound Box.
  The .bin file may be decompressed with StuffIt for the Macintosh.
  PC-based conversion and processing tools will be supported in a
  future release.

- Early versions of the MPEG Sofdec video compression tools were added
  at the last minute, for experimentation purposes only; QA testing
  has shown them to be unreliable.

- The Hitachi SH-C compiler was updated to R32.  elf2bin was updated
  to 0.83.  prfdump was updated to 0.83.  GD-Workshop was updated to
  46a.  Disk padding is now handled correctly.  The four-second track
  check during a GD-ROM burn was removed.  Codescape was updated to
  build 106.

- Initial support for the vibration peripheral was added to kaede.h,
  in the form of the KDD_FUNC_VIBRATION constant.

- The following Kamui samples were added:

    kmBlend kmCyberk kmCybr2v kmFlight kmflgt2v kmGasfl kmGas2v kmLogo
    kmLogo2v kmMarble kmNefert kmNef2v kmSample kmSeal kmSeal2v
    kmSpace kmStaind kmStnd2v kmStrips kmToyp kmToyp2v kmTrees
    TableFog VertFog

- The following Kamui demos were added:
 
    Fortune Knot Scanner Siberian Trilinear Vase Wrace

  These excellent demonstrations were written by VideoLogic and Sega
  wishes to express its gratitude for allowing these programs to be
  included in this release.

- The following Ninja samples were added:

    CnkFlat DoorOpn MCLight2

- Training content and information for Dreamcast was added to the
  \doc\training directory.  Also included are Word 97 and PowerPoint
  viewing programs, which are freely redistributable.  Three sample
  programs were included as training support.

- The sfd_mw.h header was modified to 1.01, and includes functions for
  determining and working with audio buffers, and setting display size
  and playback.  Also, sg_mwply.h was completely overhauled, and a
  MWD_PLY_ALLOC_SJBUF() function was added to wav_mw.h.

- buRewriteExecFile() was added to sg_bup.h.

- Digital audio support was added in the form of the GDFS_DAINFO
  struct in sg_gd.h.

- The sbrk() function is no longer supported; use syMalloc() and
  syFree().

- The syBtXXX() series of functions was added to sg_sybt.h for
  accessing the boot ROM service and checking the system ID.

- The following Ninja functions were added:

void njCnkSimpleMultiDrawModel( NJS_CNK_MODEL *model );
void njCnkSimpleMultiDrawObject( NJS_CNK_OBJECT *model );
void njCnkSetSimpleMultiLight(Int num);
void njCnkSetSimpleMultiLightSwitch(Int light, Int flag);
void njCnkSetSimpleMultiAmbient(Float ar, Float ag, Float ab);
void njCnkSetSimpleMultiLightColor(Int light, Float lr, Float lg, Float lb);
void njCnkSetSimpleMultiLightVector(Float vx, Float vy, Float vz);
void njCnkSetSimpleMultiLightPoint(Int light, Float px, Float py, Float pz);
void njCnkSetSimpleMultiLightRange(Int light, Float nrange, Float frange);
void njCnkSetSimpleMultiLightMatrices(void);
void njChangeTextureMemorySize(Uint32 size );
void njGarbageTexture(NJS_TEXMEMLIST *addr,Uint32 n);
NJS_TEXERRSTAT *njGetTextureErrStat(void);

- Support for bootable BIN files and CPP browser info was added to
  katana.inc.  Due to an incompatibility with one of the sample
  programs, support for targets with spaces in the target names was
  removed from katana.inc.

- The QuikTest sample program underwent a major cleanup.

Changes from R4 to R5
---------------------

Hardware
--------

- Your Set 5.2x system contains a CLX2 graphics chip and an SH-4 CPU.
  The performance of this hardware is roughly equivalent to the
  performance of the final production unit.  You can begin hardware
  performance testing with this development hardware.  However, please
  keep in mind that we will continue optimizing software performance,
  including further compiler optimizations.

  The speed of translucency sorting with the new "punch through"
  vertex format has been improved by approximately 4x.  This vertex
  format allows polygons with 1 bit of translucency information (i.e.,
  the polygon is either opaque or translucent at any point) to be
  drawn nearly as fast as standard opaque polygons.  Kamui now
  supports this type of vertex format.

- This development hardware supports audio and MIDI output.  Some
  sample content has been included for your experinmentation.

Kamui
-----

- The process for loading textures in Kamui has changed slightly.
  Kamui assumes that there exists a 16-byte header in any loaded .pvr
  file and therefore skips this memory area.  Additionally, the Kamui
  texture data must be 32-byte aligned for DMA purposes.  Therefore,
  it is necessary to manually align texture data in system memory to
  16(2n + 1) byte boundaries before attempting to use it in Kamui.

- Additionally, files must be loaded on 32-byte aligned memory
  addresses as well.  Currently, the first range of memory allocated
  by Shinobi's memory allocation routine happens to be 32-byte aligned.
  However future allocations are not necessarily aligned.  Please
  keep this in mind if you're writing your own file loader.

- The method of determining the video output device (VGA or NTSC)
  has changed.  You can use the Ninja sbInitSystem() function to
  determine whether a VGA cable is attached.

- A number of Kamui functions have been replaced by macros.  In
  particular, the kmStartVertexStrip() function has been replaced
  by kmxxGetCurrentPtr(), kmxxStartVertexStrip(), kmxxSetVertex_0(),
  and kmxxReleaseCurrentPtr().

- Kamui kas a new way to display text characters to the display, which
  is defined in dispstr.h.  Most of the Kamui sample programs use this
  new method.  The printf() function used in Codescape was
  demonstrated to be unreliable a few days before the code freeze
  date; we suggest you try using the dispstr.h method for this
  release.
 
- The sbinit.c stubs have been heavily modified to support the GD-ROM
  file system, to automatically determine the end of work RAM from
  linker information, and to automatically use the default Dreamcast
  controller instead of the old-style Maple peripheral box.  Additionally,
  sbinit.c now takes care of timer initialization and interrupt
  control.

- Twenty-one new Kamui sample programs have been added.

Ninja
-----

- Ninja now supports a chunk format model file for improved rendering
  speed.  All Ninja exporters support this format, and a command-line
  utility (NJAConv.exe) exists to convert Ninja models into the new
  format.  Old format Ninja models are still supported by the library.
  The new chunk format functions are prefixed with "njCnk".  See
  ninjaapi.h and ninjacnk2.h for a list of these functions.

- Ninja now uses a callback scheme to propagate errors to the caller.
  See ninjadef.h for details.

- Ninja now supports clipping to user-definable regions.  See the
  tileclip Ninja example to see how this works.

- Thirty-two new Ninja sample programs have been added.

Build environment
-----------------

- The compilation process no longer halts on link warnings.  To change
  this behavior, modify the HALT_ON_LINK_WARNINGS variable in
  katana.inc.

- _CLX_ and _CLX2_ must be defined for Kamui sample programs to build.

- Single and double precision constants in float.h have been
  overhauled.

- A "Start a new compilation environment" icon is added to the desktop
  as part of a standard installation, along with Codescape and GD
  Workshop icons.  (This feature can be disabled by executing a Custom
  installation.)

Codescape
---------

- Codescape now requires the presence of binary files, usually IP.BIN
  and IP0000.BIN, in order to build an executable GD-ROM image.  These
  files contain peripheral support and other information about your
  title; you will need to compile your own versions of these files.
  See the Shinobi example program.

- Codescape now supports code profiling; this functionality was broken
  in R4.
