COMPILER

  • APLIB
    • replaced appack tool by new APJ (Java APLIB packer) tool written from scratch
  • LZ4W
    • much faster compression speed
    • better exit operation

    • fixed a small bug on Sprite cutting optimisation process
    • added 'optimisation' parameter to TILESET resource
    • fixed bug on tilemap generation with base tile index used
    • fixed a mall bug in BIN resource export
    • fixed a small bug on ALIGN directive
    • optimized tile parsing
  • XGMROMBUILDER
    • now remember last used folder
  • MAKEFILE
    • added deps file (.d) support for better dependencies handling
    • added sources sub folders support (2 depth levels)
    • removed useless and undesired warnings
  • README
    • added GET STARTED part
    • major rewrite / revamp to take benefit of Markdown format (thanks to Astrofra)
    • others changes

LIBRARY

  • WARNING - IMPORTANT CHANGE
    Added SYS_doVBlankProcess(..) to replace automatic V-Int processing of SGDK.
    This was done to avoid issues with missing interrupts protection and to offer more control in general.
    So basically you should replace all your VDP_waitVSync() references with SYS_doVBlankProcess()
  • SYS
    • faster user callback interrupt handling
    • modified ROM header to enable SRAM by default
    • fixed small initialization issue
    • minor fix on SSF2 mapper initialization
    • added LOG_LEVEL setting allowing different level of log for debug (default = LOG_LEVEL_WARNING)
    • removed interrupts protection where they are not anymore useful
    • small change for more accurate detection of frame miss
  • MAP
    Added new MAP engine (map.h unit) to handle large maps / background scrolling easily from MAP resource:
    • Map* MAP_create(const MapDefinition* mapDef, VDPPlane plane, u16 baseTile);
    • void MAP_scrollTo(Map* map, u32 x, u32 y);
    • u16 MAP_getMetaTile(Map* map, u16 x, u16 y);
    • u16 MAP_getTile(Map* map, u16 x, u16 y);
    • void MAP_getMetaTilemapRect(Map* map, u16 x, u16 y, u16 w, u16 h, u16* dest);
    • void MAP_getTilemapRect(Map* map, u16 x, u16 y, u16 w, u16 h, bool column, u16* dest);
  • DMA
    • added DMA_xxxFast() methods (no 128 KB bank cross check)
    • small tweaks for bit faster DMA queue
    • tweaks in general to DMA methods
    • increased default DMA queue size (we can quickly reach 64)
  • VDP
    • fixed a small bug on VDP_drawTextBG(..) method
    • added VDP_waitVBlank() and VDP_waitVActive() methods
    • added VDP_getPlaneAddress() method (was internal first)
  • STRING
    • added support to u32/s32 type to sprintf(..) function
    • fixed fix16ToStr(..) and fix32ToStr(..) methods
  • SOUND
    • fixed a small bug on PCM command play (thanks to hsk)
    • better restoring of Z80 BUS request state
  • Z80
    • added Z80_getAndRequestBus() method
    • added loading of a dummy driver by default to keep Z80 active on init
  • replaced some u16 parameter by bool where it makes sense to have it

SAMPLE

  • Updated for SGDK 1.6 changes
  • BENCHMARK
    • minors changes (updated to version 1.31)
  • SPRITE
    • updated background to complete level dimension.
    • updated to take benefit of the new MAP resource and advanced MAP methods
    • added alternate scrolling update mode (still using new MAP unit)

SGDK 1.6 MIGRATION NOTE

  • Replace all VDP_waitVSync() references with SYS_doVBlankProcess()
  • Replace all VDP_waitVInt() references with SYS_doVBlankProcess()
