Hi Guys, as the title says I have a Hyper SF2 board, which is a probable bootleg. Ive opened the case and had a look inside. There are no extension pcbs fitting to where the eeproms go, so it looks like its a normal pcb which burned eeproms. There is also a small modification made to chip location bgsb3, where another chip has been jury-rigged into place/cross soldered, and two wires running up to the two SFX chips (eeproms 11 and 12).
The board boots as a phoenix edition, and seems to play perfectly well. The only issue Ive noticed is that there are no sounds/voice from the cpu character on player 2 side. Id appreciate if anyone can throw any light on the issue? Perhaps its something I can resolve myself....
