yes, my eprom reading services are still up on the table. =]
I can't help with re-designing the firmware or sounds. But reading the roms
and posting the bins should be no problem. Email me off list for my mailing
address, etc. I'd love to see this project move along, since i'm interested in the
same type of thing with other devices, and there is very little, if any,
information about this kind of thing on the web. It seems to be uncharted
territory, so it has to start SOMEWHERE. I'll be glad to help any little way i can.
One thing- do we know what kind of chips these are
Ryan/plutoniqe
I'll need to know the type before i read them, if it isn't printed on the chips
themselves.
