Problem with Fatal Fury Special MVS Cart

[Evan]

I recently got a fatal fury special mvs cart which is having issues. It boots up to the neo Geo intro screen but then crashes every time. Any ideas? I’ve cleaned it thoroughly.

Open the memory viewer and take a photo on that error. What does the Unibios CRC check say? Have you cleared the backup ram? What system are you running it on?

Cleared the backup ram and nothing happened. Here’s photos of the error. Crc check says it’s fine?

Got a diag bios and it says my board has passed all tests. I'm at loss to why this cart specifically doesn't work. I still assume its a ram issue but the diag says all ram works fine.

Probably a bad P2 chip.

Do you know what chip spec the p2 is? I was intending to buy an eeprom burner for my pgm and some more mvs carts I have on the way and I think ill just burn a chip to fix this.
