GBA Emulator v1.2.0

v1.2.0 — 2026-10-02

Player

• Gamepad buttons can be rebound. The Controls page shows a second keycap for every GBA button;
  click it and press a pad button (a button already in use swaps, like the keyboard). The map is
  stored as [gamepad] in settings.toml; the left stick stays a D-pad. The default shoulder
  buttons are the bumpers (LB/RB; earlier docs called them LT/RT).

Tooling

• scripts/build-mgba.ps1 builds tools/mgba-wav.exe, a headless libmgba audio capture, and
  scripts/compare-audio.py records a title set with both emulators and reports level, balance
  and alignment figures (tools/audio-ref/report.md); scripts/compare-wav.py now uses the
  same analysis. gba-test --mute-channels MASK silences PSG or FIFO channels in a capture.
• Finding, no change: our FIFO and PSG levels follow GBATEK's stated maxima; mGBA 0.10.5 mixes
  about 3 dB lower overall and its PSG another 3.5 dB lower relative to FIFO (PROGRESS.md
  "Reference audio comparison").
