Hey everyone! Last year I repaired my father's old Atari 52OO 4 port console which wouldn't power on since 1986. I replaced the all the RAM, both voltage regulators, FlipFlop chip, installed power mod and UAV S-video mod. It now works great... well sort of. Everything loads up and plays first try and looks super sharp with that S-video mod. Also fixed two controllers for a great first time experience ?
However, I noticed certain games will show glitches (example: Pac Man - Score will not reset sometimes, Centipede - The centipede part i shoot off will remain on screen, Pengo - the enemies I kill will remain on screen, QIX - will take awhile to load next stage, Choplifter - Chopper won't shoot bullets).
I ran the diagnostic rom on my flash cart. The ram checks out all good. Anyone know if I should look at or replace?!?
