o.k. i have an excite bike cart that was working fine but i saw on ebay a guy selling eproms for diffrent game i wanted donkey kong and as it has it in his list excite bike was combatable with the roms he had.after i swapped the roms out donkey kong worked great well i tried switching back to excite bike tonight it wont work as a matter of fact i makes my whole machine not work when that cart is in it. is there a certain way the roms have to be put in ther? i tried diffent ways and nothing works.
