I recently bought some PPU's one Soccer and the other just a standard RP2C04-0003. Every site I go to has the JAP version up and I did however find just 2 US versions for the eproms. The ones I have all froze on me or has lines ( kinda like when the NES glitches out) and it won't allow me to insert coins or even get past the top leader boards.
I have tested both PPUs and they work fine with other eproms (well maybe just shaking screen but thats another matter).
Any ideas to where I can get a FOR SURE working copy of Excite Bike?
