COMPILER

  • RESCOMP
    • fixed a small bug on MAP resource compression
    • implemented independant compression on MAP resource
    • XGM resource are now stored as FAR (accessible through bank switch)
    • tweaked default BALANCED sprite cutting optimization strategy to reduce a bit sprite usage over tile
    • increased maximum SPRITE width / height to 248 pixels (it was 128 pixels)
    • optimized SPRITE metadata size (divided size by 4) at the expense of slower sprite processing
    • force slow sprite cutting processing when specifying a number of iteration different from default (500000)
    • added information (rescomp.txt) about how to provide extra data (priority / palette) on tilemap for MAP and IMAGE resources
    • added support to grayscale image
    • better error reporting
  • BATCH
    • several fixes to build_adv.bat file
  • MAKEFILE
    • makefile can now define GDK variable on its own (environment variable not anymore needed)
    • fixed copy/paste typo in makelib.gen file
  • README
    • smalls changes to alternative OS solutions
    • added Raster Scroll MD graphics guide reference
    • updated credits part
    • fixed line return
  • increased maximum ROM size to 12MB
  • removed resourcemanager tool which was not used nor complete
  • added prelemenary docker support for easier SGDK usage on alternative OS (thanks to Steve Schnepp for it)

LIBRARY

  • SYS
    • added SYS_getFarDataSafe(..) method / FAR_SAFE(..) macro allowing safe access to resource crossing 512 KB banks
      SGDK methods now use FAR_SAFE(..) accessor instead of FAR(..) for bank switch mechanism
    • fixed a bug in bank switch initialization
    • better CPU load reporting
    • minor change to main(..) prototype and return execution
    • added new 'ROMHeader rom_header' variable to get easier access to ROM header infos
  • SPRITE
    • modified sprite structures to reduce metadata size (but at the expense of a bit slower processing)
    • added SPR_getVisibility(..) and SPR_isVisible(..) methods
    • now automatic sprite visibility is computed using only X position as we use it only scanline sprite usage optimization
    • made 'firstSprite' / 'lastSprite' visible
    • improved profiling
  • DMA
    • small tweak + some fixes when DMA is disabled
  • VDP
    • added VDP_setHorizontalScrollVSync() and VDP_setVerticalScrollVSync() methods to do delayed scrolling update
    • safier VDP_drawText(..) / VDP_clearText(..) methods (bounds check)
    • prevented tilemap column update when plane width is set to 128 (not possible because auto-inc register is limited to 255)
  • MAP
    • added priority info support to baseTile parameter in MAP_create(..)
  • MATH
    • removed MATH_BIG_TABLES define as it's not anymore useful with the lto
    • add clamp function (thanks de Devon Powell)
    • fix issue with rounding helpers (fix16)
  • MEMORY
    • added malloc(..) / free(..) so they forward to MEM_alloc(..) / MEM_free(..) methods
  • SOUND
    • added XGM_startPlay_FAR(..) to allow to play XGM music accessible through bank switch
  • TIMER
    • small fix on waitSubTick(..) method to take care of small wait during vblank
  • JOY
    • added JOY_writeJoypadX(..) and JOY_writeJoypadY(...) which allow to set a specific position for mouse pointer (Thanks to LIZARDRIVE)
  • small change to 'Map' and 'Sprite' structure for better doxygen documentation reference

SAMPLE

  • reworked folder structure
  • added new basic HELLO_WORLD sample
  • added BAD APPLE demo sample (to exhibit SGDK bank switching mechanism)
  • added new WOBBLE fx sample (thanks to Andreas Dietrich for it)
  • added new SCALING fx sample (thanks to Andreas Dietrich for it)
  • SPRITE sample renamed to SONIC
  • BENCHMARK
    • better score computation for Sprite part (also now comparable to others tests)
