Upgrading GGXX to GGAC Problems

Hello, I have recently purchased the GD-Rom for Guilty Gear : Accent Core (JAP) to replace the old version of Guilty Gear XX (USA). Initially, there were errors concerning Naomi board errors 1 and 2, however, I have recently bought the EPR-B23607 in hopes of getting rid of this problem. There is a new problem now. When I put the new EPR inside, there is no output display showing up. Any suggestions on how to fix this?

I believe all of the B revision EPROM BIOS chips (23605B or later) are for the Naomi 2, so unless you're running a Naomi 2 mobo, that could be your problem.

EPR-23xxx bioses are indeed for naomi 2 only.

Darkzero would you mind giving the serial written on your accent core gd rom ? (starts with gdl-xxx) and the number on your IC (starts with 253-xxx) ?



thx ahead.
