embedded chip question

[jm]

I have a game I took apart and on the pcb it has:

OPCVO
76021300
9712 REV.B

These turn nothing up in Google.

If I want to know what Microprocessor this company used for their
game, where would I start (besides asking them)? Thank you.

The chip itself is not in a plastic case with legs, rather it is the
little "square" chip with the leads attached directly, hard melted
plastic covering the chip. I can't see the chip, so I don't know if
it has markings on it.

Thanks again.

That's "chip-on-board", and there's essentially no way to find out
other than to dissolve the epoxy blob with hydrofluoric acid and
reverse-engineer the chip itself.

It's much cheaper to just buy a new micro. ;-)

The reason for looking at the existing one was for just that, so I'd
know what kind of chip to get. That's what I am really after.
