Changelog

0.9

Added

• Nintendo DS / DSi support (b80e7bd) — new platform backend built on
  devkitARM and libnds, running alongside the existing GBA target from a
  unified, cross-platform game core. Includes DS-specific graphics
  (Mode_FB0 framebuffer), sound (ARM7-driven), input, and SD-card saves;
  Makefile support for per-mod .nds builds with embedded levels and
  metadata; tooling to generate DS icon BMPs for .nds packaging; and
  updated README documentation.
• Rider & moto color customization (502a042) — new CUSTOMIZE screen
  reached from Settings. Recolor the helmet, rider suit, and bike from a
  shared 6-color palette (Up/Down to pick the part, Left/Right to cycle
  color) with a live bike preview. Choices are saved to SRAM and applied
  everywhere the bike is drawn (splash, gameplay, finish). Because MODE3
  has no hardware palette, recoloring uses build-time tinted sprite
  variants emitted by convert_assets.py — one hue-shifted copy per
  palette color, at zero per-frame cost. Defaults reproduce the original
  art (yellow helmet, blue suit, red bike).

Changed

• ROM metadata customization (c4195c4) — gbafix.py now accepts
  title, game code, maker code, and version arguments; the Makefile passes
  this metadata through at build time.

⚠️ Save compatibility

• The GBA build resets existing saves after this update. SAVE_MAGIC
  was bumped (RGD4 → RGD5) when the three rider/moto color-index fields
  were added to SaveData, so older saves are detected as incompatible
  and cleanly reset to defaults (default colors, progress cleared).
