@mud2005 said in lr-atari800 "ATARI COMPUTER - MEMO PAD" Blue Screen:

I believe that was it, above the system setting click "create game options file". Also in /opt/retropie/configs/atari5200/retroarch-core-options.cfg I have atari800_system = "5200" I honestly can't remember if that was there previously or I added it, but everything is working great, I can launch 5200 and 800 games now w/o have to mess with the F1 menu in atari800 emulator :)
I only tested on a few games, but so far so good.

Strange because I do not have such file on my latest RetroPie:
