Thanks @sk8er000, others have also confirmed it working fine on 171-5987 romboards.
I've played all the game in single player mode using all 3 players and 2 players mode (not enough friends to try 3 players mode ).
Tried various difficulties and listened all the sound test menu.
Everything is working from my tests!
Great job @Apocalypse
