SGDK 1.51 (april 2020)

COMPILER

• APPACK
  • fixed build for 32 and 64 bit linux (thanks doragasu)
• LZ4W
  • minor fix
• RESCOMP
  • added new sprite optimization options to SPRITE resource (see rescomp.txt for details)
  • minor tweak on binary export order (can save some bytes with LZ4W compression)
  • fixed resource duplication bug
• XGMTOOL
  • fixed VGM loop

LIBRARY

• fixed corrupted library binaries which were displaying a blank screen on some MD models
• MEMORY
  • fixed a minor in memory packing operation
  • added MEM_pack() here and there to avoid memory fragmentation
• VDP
  • fixed getAdjustedVCounterInternal(..) which could return value > 255 in some rare situation
  • moved VDP DMA busy checking on reset (better to do it before accessing VDP)
  • VDP_setPlaneSize(..):
    • added constraint on plane size
    • fixed maps start address calculation (when VRAM setup is asked)
  • minor change in VDP_drawImageEx(..) to do setTileMap(..) operation using CPU (DMA is actually slower here)
• added SYS_showFrameLoad() / SYS_hideFrameLoad() methods to monitor CPU frame load.
• always load font using CPU in reset process (safer)
• fixed String unit build when ENABLE_NEWLIB set (thanks doragasu)
• improved documentation in Joy unit (thanks Chilly Willy) and VDP (regarding DMA QUEUE usage specifically)

SAMPLE

• reduced memory usage on sample which use Bitmap mode by reducing DMA allocated memory
• SPRITE
  • added SYS_showFrameLoad() showcase
