Has anyone ever customized any sound eproms? Like adding your own music or speech to replace the original? It seems like it could be done if one knows what A/D conversion routine needs to be used and at what memory addresses each sound resides in.
I know this can be done on some old drum machines and such for custom percussion sounds, etc.
Still, was wondering if there are any good websites that deals with customizing PBall sound chips or if anyone has tried or done it.
Happy 4th of July to ALL
