It's my first time converting a system 32 board, and wondered if anyone had some advice. Started with a working dark edge board, and trying to convert it to dbz vrvs

Right now, I'm able to boot the game, add credits, and get into the test menu.
The rom test checks out, all the buttons are working in the input test... but when I get to the initial screen to start the game, nothing happens.
The black screen will get a smudge on the screen for a split second, as if it's restarting.
I'm not able to get to an attract screen, or anywhere past a black screen that says the number of credits. I can hear gokus scream when adding credits.

So far I've:
-burned the decrypted roms
-removed the security battery
-burned a new GAL from pld archive
-made sure my jumper settings matched with Guru's system32 page
-checked voltage at the edge connector

Thanks in advance

You swapped the cpu? What speed are your eproms?
I used these for the proms

STMicroelectronics M27C160-100F1 27C160 16MBIT UV EPROM CDIP40

I didnt swap the cpu. Just replaced the gal

But i did use the unlocked jed file, rather than bruteforced version. Unsure if either file is specific to atf/gal.
