[SOLVED] X-Men 2P Conversion & Sound Module Help

[kikaso]

I have a Konami 4-player X-Men board I’m looking to convert to 2-player. I replaced the mask ROMs at 10D and 10F with burned EPROMs with the corresponding 2P files from xmen2pu but now I’m getting a RAM error At 13B. The RAM error goes away if I replace with original mask ROMs. The EPROMs were burned for me by BuyICNow. I successfully converted a Simpsons board to 2P using EPROMs from the same order. Does anyone know where I went wrong?

Second question; does anyone have the SMD capacitor list for the X-Men sound module? Looking to recap before they leak.

Thanks!

After converting the board from 4 to 2 Players you must re-initialize the serial EEPROM @13B by holding the test switch while powering the board up and keep pressing down it as long as the whole process has ended.
Attached is the capacitors chart of the '054544' audio module.

It worked! Thanks so much, @caius
