thetallguy24 Posted May 12, 2015 Share Posted May 12, 2015 I have a 7800 that powers on fine to the title screen but craps out after. I've tried two 7800 games with the same results. I know the games work because I have another 7800. Any suggestions on the issue? Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted May 12, 2015 Share Posted May 12, 2015 First thought, bad/dirty connector, have you tried a 2600 game yet? Quote Link to comment Share on other sites More sharing options...
thetallguy24 Posted May 12, 2015 Author Share Posted May 12, 2015 First thought, bad/dirty connector, have you tried a 2600 game yet? Yeah I put in Battlezone, which works great on my other 7800. It runs, but its very dark with some funky horizontal lines. Quote Link to comment Share on other sites More sharing options...

thetallguy24 Posted May 15, 2015 Author Share Posted May 15, 2015 After more testing, I was able to get several 2600 games to work just fine. However, I tested 6 7800 games, and only one worked (Pole Position 2). The rest (Joust, Ms. Pac-man, Galaga, Centipede, cut out after the Atari intro screen. Is there a separate chip or capacitor that only affects 7800 games that could be out? Quote Link to comment Share on other sites More sharing options...
Jinks Posted May 16, 2015 Share Posted May 16, 2015 Voltage regulator maybe? 7800 games running the Maria need more juice. Or not... Quote Link to comment Share on other sites More sharing options...
+DrVenkman Posted May 16, 2015 Share Posted May 16, 2015 Voltage regulator maybe? 7800 games running the Maria need more juice. Or not... Another possibility is the MARIA chip itself. It's not used in 2600 games at all. If it's getting flaky, some games might stress it more than others and cause problems. Quote Link to comment Share on other sites More sharing options...
