Graphics problems with a cps2 progear conversion

So, I decided to make a progear out of a suicided xmen cota and it has graphics problems.... So far, i've checked all the roms and compared the checksums with the original files... All ok. I've reflowed the solder on a lot of the pins (incase of cracks), I've cleaned everything I can think of to clean, I've checked and rechecked the jumpers... I'm stumped. Just checked using razoola's suicide checker and that's also got weird things happening.


The original graphics issues look like this..


Seems to mainly effect the background graphics, sounds and gameplay are fine though...

If Raz's rom is not running properly you might have problems elsewhere like dirty connections, bad ram, lifted custom, damaged traces...etc

Yeah, afraid it would be something like that. Just not sure where to start.
