  • Added docs/FORK_AUDIT.md, covering trash80/mGB, vifino/mGB, and notable sibling forks.
  • Ported the dalton-tulou / tonytwostep frequency-table lookup fix for trash80/mGB issue 3.

Validation

Tested ROM SHA-1: 7a1c4dd26b05d5f16ad2c449cd36efa2efcf2011

Regression results:

  • make -C Source test GBDK_HOME="$HOME/.cache/gbdk-2020/4.5.0/gbdk": passed.
  • make -C Source sameboy-midi-regression GBDK_HOME="$HOME/.cache/gbdk-2020/4.5.0/gbdk": 171 SameBoy MIDI/link runs passed, 0 failures.

Two informational APU-hash differences remain for poly_ch5_three_notes versus the old ROM in CGB/DMG; these are expected for the current poly behavior and did not fail the regression suite.
