  • README
    • fixed assembly (asm target) generation
    • added links + smalls updates here and there

LIBRARY

  • SPRITE:
    Rewrote the sprite engine to get rid of hardware sprite allocation (note that the legacy sprite engine
    is still accessible through the config.h file as it can be useful for sprite multiplexing).
    • better hardware sprite usage
    • general simplification of the API
    • lighter 'Sprite' structure
    • re-introduced Y position in visibility computation
    • lot of optimisations done to maintain same or get higher level of performance
    • added SPR_getAnimationDone(..) method to know if current playing animation reached the last frame
    • added SPR_getUsedVDPSprite() method to know how many hardware sprite are currently in use.
    • added SPR_enableVDPSpriteChecking() / SPR_disableVDPSpriteChecking() methods
    • added SPR_getFreeVRAM() and SPR_getLargestFreeVRAMBlock() methods
    • keep same behavior in debug / release build
  • OBJECT
    • small fix in POOL_find(..) method
  • MATH
    • transformed some macros to methods for better type checking (can also help the compiler)
  • CONSOLE
    • added TTY console support (added as module - thanks to Andreas Dietrich for it)
  • VDP
    • modified MAX_VDP_SPRITE to SAT_MAX_SIZE as max displayable sprite depend from horizontal reolution
    • disable VDP during VDP_resetScreen() process (faster operation)
    • small fix on VDP_waitVSync() and VDP_waitVActive() methods to take care of VDP disable state
  • SYS
    • added SYS_nextFrame() method (just an alias to SYS_doVBlankProcess)
    • added SYS_resetBanks(), SYS_getNextFarAccessRegion() and SYS_setNextFarAccessRegion() methods
    • fixed a bug with soft reset + general safer soft reset operation
    • added SYS_getShowFrameLoad() method
    • fixed small bug in TSK_init()
  • Z80
    • several fixes and method updates for safer operation
  • SOUND
    • added XGM_setPCM_FAR(..) and XGM_setPCMFast_FAR(..) to allow playing PCM through bank switch
    • added YM2612_readStatus() method
  • JOY
    • added JOY_getEventHandler() method (useful for saving / restoring callback)
  • SAVE
    • added flash save support (added as module - thanks to doragasu for it)
  • MISC
    • tweaked / improved readability of lz4w_unpack (thanks to HpMan)
  • deprecated methods and definitions now generate compilation error
  • added NO_INLINE definition when we want to force no inlining
  • forced NO_INLINE on some larges functions to avoid code growing too much
  • added megaWifi README file
  • documentation updates
  • smalls fixes, general cleanup, some refactoring..

SAMPLE

  • BENCHMARK
    • added new large scroll performance test
    • added new big sprite tests
    • reworked scoring (making it not comparable to previous versions unfortunately)
    • small fixes
  • updated samples to last SGDK

SGDK 1.90 MIGRATION NOTE

  • removed spriteIndex parameter from SPR_addSpriteEx(..) function
  • removed SPR_FLAG_AUTO_SPRITE_ALLOC definition (not anymore useful)
  • removed resetz80 parameter from Z80_upload(..) function (it's always reset now)
  • Z80_clear(..) doesn't take any parameters now (it always clears all the Z80 RAM now)
