This may be a really silly question, but I somehow managed to press "X" which then changed the Advancemenu "display" to a red square and no roms... Because the config is saved at exit, I cannot figure how tho reset the Advancemenu. I also tried to look for "x" in the deafult controls and my advmenu.rc, but it seems it's not defined... What did I actually do?
Running the latest Groovyarcade (linux)
EDIT: It was actually "5" what I pressed. Got back by pressing F7 (next emulator)
