Quoted from barakandl:Gamatron by Pinstar's daughter card has a 100% identical to SB300 sound circuit on it. It sounds the same as a stock MPU200 set for F2K + SB300. Mine sounded no different after switching from the daughter card to a MPU+ sb300.
The SB300 is highly sensitive to the CPU's clock...
