I'd like to ask for your help.
I've got a Metal Slug 2 cartridge which has a problem.
Unibios is reporting an illegal instruction on address 002E0000.
Is that on the P ROM?
I've modded the cartridge with the speed fix but I've put a socket on it and I can switch to the original chip - however I get the same error with the original one.
It used to work fine even after the mod and I put it away a few months back and now that I tried to play again I'm getting this error.
I've double checked the soldering and run the soldering iron over them to make sure.
I've cleaned the edge connector as well.
I'd appreciate your help.
