@substring I've tried what you suggested, but it doesn't work. I keep getting the same: I select the game and then, I am brought back to the game menu. Just to say that I changed ALL the "videomodes" for "default" in the "recalbox.conf" file. And I really think you guys should let available the older versions of Recalbox.

Yes, I am experiencing problems with SNES, Neo Geo and Mega Drive. When I select a game, it just goes back to the game selection menu. I really don't know what could be happening. I am using Recalbox 6.1.
