COMPILER

  • RESCOMP
    • added new NEAR function to force NEAR location of binary data (read rescomp.txt file for more info)
    • fixed a small bug on MAP resource where it was using flipped version of a tile even if tileset was containing non flipped version
    • better optimisation process for large sprites (close to the limit of 16 hardware sprites)
    • many small fixes, tweaks and improvements to sprite cutting process
    • added duplicated sprite frame optimization
    • fixed typo on 2BPP to 8BPP image conversion
    • added information on MAP resource compilation
    • WAV resource can now be set as FAR (bank switch)
    • fixed sample output override for WAV resource (needed for Bad Apple sample which use a custom ADPCM2 driver)
    • fixed a possible bug in duplicated resource symbol
  • APJ
    • fixed cost computation (bit better compression)
    • fixed encoding for short match with long offset
    • more infos on encoding errors
  • LINK
    • increased theoretical max ROM size to ~3.8GB (using bank switch)
  • README
    • added MarsDev project reference
    • added And-0 documentation references
  • DOCKER
    • use lighter docker image
    • improved / fixed docker script (thanks to all contributors for that)
  • rewrote sizebnd tool in Java and added auto checksum feature.

LIBRARY

  • SPRITE
    • fixed a bug where some sprites wouldn't be properly hidden in rare occasion
    • automatically update VRAM region location when VRAM mapping changed
    • VRAM region can be remapped if needed on defrag operation
    • added sprite validity check in 'debug' build
  • VDP
    • VDP_resetScreen() now also reset VSRAM
    • updated VRAM mapping for 64x64 plane size to allow full window map
    • use new mul/div/mod functions for small performance improvement on some functions
  • MAP
    • fixed a decoding bug when we had consecutive same row block offset
    • fixed MAP scrolling update when using TILE/LINE horizontal scrolling mode
  • MATH
    • added fix32Avg(..) and fix16Avg(..) methods
    • added mulu/muls/divu/divs/modu/mods/divmodu/divmods(..) functions which allow to directly use the 68000 mul/div instruction (GCC doesn't always use them correctly)
  • SYS
    • added ROM_SIZE definition to get ROM size
    • added SYS_getFarDataEx(..) and SYS_getFarDataSafeEx(..) methods
    • added SYS_isCrossingBank(..) method
    • fixed RAM mapping for bank switching with ROM larger than 12MB
    • reset banks only when bank switch is enabled (may help with Everdrive X3)
    • added SYS_setVBlankCallback(..) method
    • added SYS_computeChecksum() and SYS_isChecksumOk() methods
  • DMA
    • lowered default PAL buffer capacity (DMA_BUFFER_SIZE_PAL_LOW) to spare memory
    • HALT_Z80_ON_DMA is now enabled by default for the sake of safety
    • added DMA_canQueue(..) method and small fix on transferSize calculation
    • fixed a stupid bug in DMA_doDma(..) on 128K bank crossing
    • removed some VDP_waitDMACompletion() check for performance reason (developer need to do it by himself)
  • PAL
    • added TransfertMethod parameter to set palette colors methods
    • made 'fadeCurrentPal' and 'fadeEndPal' variables visible (can be useful)
  • SOUND / XGM
    • protected XGM_xxx methods against interrupts
    • fixed XGM_pausePlay(..) which wasn't always muting all sound (thanks to BigEvilCorporation for the fix)
    • fixed potential PENDING_FRM overflow (mutual change)
    • XGM play / pause / resume commands are now exclusive (cannot be pending at same time)
    • full YM reset on YM2612_reset()
  • BITMAP
    • fixed VRAM organization for Bitmap mode (restore 64x32 plane size on exit)
    • use new mul/div/mod functions for small performance improvement on BMP_scale(..) function
  • ROM HEADER
    • updated default SRAM size to 64 KB
  • JOY
    • use the correct bits to detect 3-button.
    • tried to compensate 6 button read to avoid the UP+DOWN issue state (emulator or unofficial controllers)
  • small changes for better/safer soft reset behavior
  • replaced some waitVSync() by SYS_doVBlankProcess()
  • more detailed error / warning logs in debug build
  • documentation fixes and updates
  • cleanup, removed old deprecated units / headers

SAMPLE

  • SONIC
    • fixed DMA buffer size for initial MAP update
