Probibly best to find some one with a programer, Send them some chips, they ID them, Then return the chips! :)

Terra Cresta with crappy cheapo YM2208 sound chip common to bootlegs.

I just fixed up one of these for Tom removing the crappy sound chip rider board and sticking a YM3526 like whats on the original PCBs, you also have to reprogram 3 roms. The crappy chip only uses 2 roms while the YM3526 uses 3 27128s.

Funnily enough he bought this pcb off you from ebay which looked like it was dragged through mud :D. Needless to say i brought it back from the dead.

attached are some before and after shots.
