COMPILER

  • RESCOMP
    • added ALIGN directive (read rescomp.txt for more information about it)
    • added UNGROUP directive (read rescomp.txt for more information about it)
    • added 'compression' and 'far' field to BIN resource
    • replaced Map structure export by TileMap
    • minor optimization in building IMAGE tilemap
      plain tiles are now ignored (taken from system tiles) when using a base tile index offset for tilemap (mapbase parameter in IMAGE resource)
    • more flexible resource compilation
      • ignore palette and priority for transparent pixel
      • sprite can have their palette not starting at index 0
    • reorganized resource data export order for better LZ4W compression and bank switch support
    • added support for 1bpp and 2bpp indexed color images
    • faster LZ4W tool call (embeded in rescomp now)
    • preserve resource order for better BIN data compression with LZ4W
    • more constrained sprite cutting process depending chosen optimization strategy
    • minor fix to allow using bit 7 (color index >= 128) in IMAGE resource as priority bit in tilemap
    • simplified / fixed binary compression block with alignment
    • fixed a bug on possible duplicated resource export
    • fixed Circle collision type export
    • now return -1 as exit code on error
    • replaced FileWriter by StringBuffer (faster and safer)
    • minor changes and improvements to rescomp.txt file
  • XGMTOOL
    • fixed a small bug during sample conversion processing
  • XGMROMBUILDER
    • updated to last XGMTool and XGM driver version
  • LZ4W
    • fixed LZ4W compression which could failed in very are case
  • BINTOS
    • fixed data section (it was .text instead of .rodata)
  • MAKEFILE
    • updated 'release' target to generate symbol.txt file (always interesting to have)
    • show more warnings
  • forced no inlining of memset / memcpy methods to fix LTO agressive optimization issue

LIBRARY

  • SYS
    • added bank switch support using SSF2 mapper (allow ROM > 4MB)
      • use ENABLE_BANK_SWITCH flag in config.h file to enable bank siwtch support in SGDK
      • added FAR(..) directive to access a resource through bank switch if required
      • added SYS_getBank(..) / SYS_setBank(..) methods
    • moved RAM initialization to sys.c unit and added support for bank crossing (more control on it)
    • minors changes to reset methods (simpler)
    • added ROM and RAM constants (yeah, why not ^^)
  • SPRITE
    • added sprite frame change event callback (using SPR_setFrameChangeCallback(..) method)
    • added SPR_loadAllFrames(..) to (pre)load all frames data of a SpriteDefinition to VRAM
    • removed unpack buffer (replaced by DMA buffer and new DMA_QUEUE_COPY method)
    • fixed a small issue with delayed update
    • fixed a bug on SPR_setDefinition(..) (can display glitches as some sprites weren't always properly hidden)
    • fixed internal sprite link (could occasionaly let some phantom and glitched sprites visible)
    • added out of range index detection for animation and frame (debug build only)
  • DMA
    • added new DMA buffer for easier and better DMA queue management
      • added 'bufferSize' parameter to DMA_initEx(..) function
      • added DMA_setBufferSize(..) and DMA_setBufferSizeToDefault() functions to set the temporary DMA buffer size
      • added new DMA_QUEUE_COPY transfer method (TransferMethod enum) to copy data to a temporary buffer before transfer actually occurs
      • added DMA_allocateAndQueueDma(..) function which return a temporary buffer and queue a DMA transfer from it
      • added DMA_allocateTemp(..) and DMA_releaseTemp(..) methods to allocate memory from DMA temporary buffer (use that safely)
      • added DMA_copyAndQueueDma(..) function which copy data to transfer to a temporary buffer and queue the DMA transfer
    • added a new generic DMA_transfer(..) function
    • added DMA_doCPUCopy(..) function to do a CPU copy to VRAM/CRAM/VSRAM
    • added DMA_getMaxQueueSize() and DMA_setMaxQueueSize() to get and set the queue size.
    • passed the DMA queue flush loop in assembly for better control (and also faster operation as GCC was dumb about it)
    • safer DMA operation on DMA_doDMA(..)
    • added DMA_initEx(..) and simplified DMA_init()
    • added new DMA_DISABLED flag in config.h to completely disable DMA support in SGDK (for debug purpose)
    • fix for HALT_Z80_ON_DMA (stupid typo)
  • VDP
    • many refactoring (see refactoring section at bottom)
    • TILE_USERMAXINDEX now take allocated VRAM for sprite engine in account !
    • added TILE_SPRITEINDEX constant to get base tile index for the Sprite Engine
    • added tilemap row update methods
      • VDP_setTileMapDataRow(..) / VDP_setTileMapDataRowEx(..)
      • VDP_setTileMapRow(..) / VDP_setTileMapRowEx(..)
    • added tilemap column update methods
      • VDP_setTileMapDataColumnFast(..) / VDP_setTileMapDataColumn(..) / VDP_setTileMapDataColumnEx(..)
      • VDP_setTileMapColumn(..) / VDP_setTileMapColumnEx(..)
    • added TransferMethod parameter to many tilemap set methods
    • added tilemap wrapping support to VDP_setTileMap(..) and VDP_setTileMapEx(..) methods.
    • added setupVram parameter to VDP_setPlaneSize(..) function
    • removed vdpSpriteCacheQueue table (replaced by new DMA_QUEUE_COPY)
    • re-introduced VDP_loadTileData(..) method in vdp_tile.c unit (no more assembly code for this one)
    • moved font loading in VDP_resetScreen() method (fix)
  • PALETTE
    • fixed palette fading so it correctly trigger during vblank (avoid CRAM dot)
    • fixed minor issue in palette fading (sometime not properly doing last fade step)
  • MEMORY
    • fixed MEM_getLargestFreeBlock(..) method
    • added MEM_pack() method to help reducing memory fragmentation
    • removed MEM_init() access as it's not safe to call it externally
    • increased stack size to 0xA00
  • MATHS
    • fixed getLog2Int(..) method
    • replaced sin tabs to use FIX32/FIX16 (thanks to FireRat for the generator)
  • TYPES
    • added new rorxx(..) / rolxx(..) functions which are correctly turned into ROR / ROL instruction when optimization are enabled
  • Z80
    • fixed Z80 enable restoration on DMA
  • general cleanup and refactoring

SAMPLE

  • Updated for SGDK 1.5 changes
  • BENCHMARK
    • added memory information at startup
    • some changes to adapt to last SGDK
  • SPRITE
    • updated resources to use large backgrounds
    • updated to support long scrolling > 512 px (vertical and horizontal) !
    • as collision is not implemented, added physic settings using START button so we can play with vertical scrolling too
    • enemies sprites frames preloaded and animated using new Sprite engine features
      Showcase of SPR_loadAllFrames(..) and SPR_setFrameChangeCallback(..) methods
  • XGMPlayer
    • updated for easier integration in XGM ROM Builder tool
