Dear All, I am happy GS user since 2 weeks. Managed to install RetroArch atari800 core, and got XEX games to run. But… I have a keyboard/controller issue. Many games do not recognize keys to START, i.e. HERO, River Raid, etc. I only managed to start Donkey Kong. Seems to be some mapping issue. I was trying to play around with RetroArch re-mapping but got nowhere. Anyone tried, any solution please?
