Bubble Bobble (bootleg) text corruption

[insx]

Hi Folks

I removed all my ROMs to help with another project and after reinstalling them, I get this slight text/graphical corruption:

I'm assuming this is down to a ROM as that's what I've been messing around with but does anyone know which one (or if it's something else)? I'm a bit reluctant to start pulling all the ROMs again if I don't have to.

Cheers

Check you haven’t bent any ROM pins under the chip when putting them back, it’s easily done.

I really don't know what was wrong or how I fixed it but I got there in the end. I couldn't find any bent legs or bad code but after several hours of messing around, I got it going. The only thing I could come up with is that a socket somewhere is a bit iffy.
