Any Banpresto experts here

I have a Banpresto board set (not working) about 1993-94 vintage.

The mask roms have KA2 on them, the eproms are ZR040P which I assume are the same as 27C040 ?, romident does not recognise these ?
Maybe not dumped in mame yet.

It is a single mobo with a couple of small daughter boards.

Do you have a picture of the board?? Some peeps might be able to identify the board from a good picture. What kinda CPUs are on it?

Are you getting a good read from the ROMs? The problem with Romident is that it actually compares the hashes instead of real 'data', so if the ROM read is just a bit off, the hash result wouldn't match.

A good question, the day after reading, the programmer died. Turned out to be a cooked L165V variable voltage regulator. Maybe it was defective during the read process, read twice with the same crcs though. Will do another compare.
