SGDK 1.40 (may 2019)

on GitHub

COMPILER

• RESCOMP
  • rewrote from scratch in java for easier evolution and easy multi OS support.
  • added smart sprite cutting (detect empty space in sprite)
  • many changes on SPRITE resource, don't forget to read the rescomp.txt file to see changes about this resource.
  • can now disable map optimization for IMAGE resources (see rescomp.txt for more information)
• LZ4W
  • added code sources (java)
  • fixed compression using previous data block in ROM (updated packer to version 1.4)
• BINTOS
  • fixed a stupid bug on path.
• added XGM ROM builder tool sources.
• removed RESCOMP (C version), WAVTORAW, TFMCOM and Z80DASM tools.
• added Visual Studio template.

LIBRARY

• SYS
  • added SYS_setVIntAligned(..) method to force V-Int callback to align process on VBlank.
    IMPORTANT: by default now SGDK does align the V-Int processing to VBlank so you need to disable it if you don't want it !
  • added SYS_getCPULoad() to return CPU load estimation.
  • added SYS_resetMissedFrames() / SYS_getMissedFrames() methods.
• DMA
  • simplified DMA over capacity strategy
  • minor change in debug log message
• SPRITE
  • renamed SPR_init(..) to SPR_initEx(..) so now SPR_init() doesn't require any parameters by default.
  • removed 'maxSprite' parameter from Sprite Engine initialization (alays use max available).
  • added delayed frame update support.
  • added SPR_FLAG_DISABLE_DELAYED_FRAME_UPDATE flag to disable the delayed frame update (when we are running out of DMA capacity).
  • added SPR_setDelayedFrameUpdate() to change the delayed frame update state for a sprite.
  • added SPR_FLAG_INSERT_HEAD flag to allow adding new sprite in first position (instead of last position by default)
  • added SPR_defragVRAM() method to force VRAM defragmentation
  • added SPR_addSpriteSafe(..) and SPR_addSpriteExSafe(..) methods (automatically do VRAM defrag if needed)
  • fixed a bug where the last VDP sprite attribute weren't always correctly updated with visibility set to AUTO_SLOW.
  • fixed a bug a sprite couldn't be allocated.
  • fixed sprite visibility state when the number of used sprite changed.
  • many changes to sprite structures (better handling of flip info, better ROM usage...)
• VDP
  • added VDP_showCPULoad() method to display CPU load
  • added VDP_waitVInt() method to wait until next VInt to happen.
  • removed 'waitvsync' parameter for VDP_initFading(..) and VDP_doStepFading(..) methods (we always want VSync here)
  • simplified / tweaked macros for VDP control writes
• VRAM
  • added VRAM_getAllocated(..) and VRAM_getLargestFreeBlock(..) methods
• TYPE
  • added bool type
  • replaced u16 by bool where it needs to be
• MATHS
  • updated fix32Mul() and fix32Div() definition (again, trying to find the best compromize)
  • added new missing structures as Vect2D_f32, Mat2D_f32, Vect3D_xx...
  • added f16 and f32 as shorcut of fix16 and fix32 types.
  • added short typedefs (V2u16 = Vect2D_u16, V2f32 = Vect2D_f32, M2f16 = Mat2D_f16, M3f32 = Mat3D_f32)
• PALETTE
  • removed index field from Palette structure
• JOY
  • added checking for mouse / multipad read operation to avoid timeout operation when mouse or multipad is not present.
• Z80
  • added volatile access for safety
• TIMER
  • improved waitMs(..) method to be more accurate on small wait.
  • tweaked getSubTick() method (need testing, possible regression)
• STRING
  • fixed and optimized uintToStr() method
• TOOL
  • memory allocation methods for unpacking now always use deep allocation regardless of the compression used (simpler and less bug prone)
  • fixed LZ4W decompression using previous data block
• fixed variable initialization (last byte was not always properly initialized)
• added HALT_Z80_ON_IO define (config.h) to force Z80 halt on IO port access.
• new awesome SGDK logo (Thanks a tons to Lizardrive for making it !)
• removed useless sound drivers (MVS, TFM and VGM)
• removed old TILE_CACHE unit (replaced by VRAM unit)
• removed useless zlib
• many refactoring (sorry for that, you will need to update your old code)
• many tweaks / cleanup

SAMPLE

• updated all samples to take care of last changes made in SGDK
• BENCHMARK
  • tweaked big sprite test to disable the delayed sprite update (new sprite engine feature)
  • fixed sheet size (new rescomp don't allow it)
