Well, I thought I was doing ok on this scratch build cabinet project. However I am thinking I may have a RAM problem regardless of what the game says in diagnostics.
I think this looks a little off and a little fuzzy.
First of all, are there any Galaga Pro's out there that repair these on a normal basis?
Secondly, any guesses? Should I just up and remove all 8 2147's and place the 2 2148's without knowing for sure what the problem is? I don't know a good way to test 2147's in circuit.
Any help is greatly appreciated.
