Game-Specific Issues
The High Speed schematics for the sound section (page 3 of 4 of the MPU board) have some incorrect info. The error shows the signals coming from U6 (74LS74) and U7 (74LS139) going to the wrong sound ROMs. Flip-flopping the U21 & U22 chips resolves the errors. No visible revisions or notes are listed between the incorrect and correct schematics.
