You may recall that the AtGames Firecore Consoles have some really bad PSG and FM pitches. I, with some help from Big Evil Corporation's blog post, Taming The Firecore Part 1, have made some code to fix the sound on AtGames consoles, without having to use Neto's Bootloader or Neto MS-DOS. I'll update this when I figure out how to detect a Firecore. The Code: In The label Where Your Sound Driver is loaded, add: Code: move.w #$FFFF, $00000000 ; Latch 0x0000 move.b #$78, $00B00018 ; Write new PSG frequency move.b #$26, $00B01054 ; Write new FM frequency move.b #$20, $00B01055 ; Write new FM clock move.w #$FFF7, $00000000 ; Un-latch Label Names: Sonic 1 AS (GitHub, 2023): DACDriverLoad or SoundDriverLoad (Old Label) Sonic 2 (GitHub, 2023): SoundDriverLoad Sonic 3&K (GitHub, 2023): SndDrvInit
