v0.9

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).

v0.8

Changelog

All notable changes to ReGravity Defied are documented here.

[0.8] - 2026-06-18

Added

• Version number (0.8) shown on the About screen and baked into the build
  filenames (e.g. ReGravity_Defied_classic_v0.8.gba) via a single VERSION
  variable in the Makefile.
• Decorative bike animation on the splash screen.
• Sound settings now persist to SRAM and are restored on launch.

Fixed

• Lap timer no longer starts the instant a level opens. Timing now begins when
  the front wheel reaches the start flag (the first track point past the start
  threshold), matching where the flag is drawn.
• Flag depth ordering: the rider now passes between a flag's two poles — the
  far (ribbon-side) pole draws behind the moto and the near (riding-side) pole
  draws in front, instead of the moto hiding or being hidden by both.
• Wilhelm scream now has trailing silence in its sample buffer to prevent audio
  pops at the end of playback.

Performance

• Precompute per-frame physics terms (gravity term and per-input-state
  inverse-mass tables) so the solver avoids redundant 64-bit software divides
  on every substep. Output is bit-identical.
