    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. ;-)

    Cheers!

    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.

    more often than not, they're not an off-the-shelf micro; rather they're a
    custom designed-manufactured ASIC.

    It's actually cheaper to mass-produce them that way (Think masked ROM vs
    EPROM).
