Hi everyone, I've had a similar problem with my lynx 2 freezing at the title screen, I've had the lynx since 1994 but it worked fine before I stored it away in 99, went to try it out and it was glitching with the graphics and freezing, I cleaned and checked the cartridge slot, replaced all the caps, checked the internal voltages and they seem to be good, I've replaced the ram, checked the outputs with a scope on the chips and ram, everything seems to be sending data so I'm completely stumped as to what it could be, I have tried the games on another lynx 2 and they seem to work fine. I've tried the slot pin bridge technique to see the insert game screen but even that seems corrupted.
I've included a list of games I have that freeze or run with corruption:
Working with glitchy graphics:
Ryger
Gates of Zendocoo
Scrapyard Dog
Batman Returns
Freezing at title:
Blue Lightening
Gauntlet
Todd's Adventures in Slimeworld
Block Out
California Games
APB
RoadBlaster
Rampage
Pac-Land
