Do you still need an I/o hooked up to use this? I have all the components I need except for an I/o and would like to play a game, but I think I’m out of luck until an I/o shows up.
then click the google docs link to see which games will allow booting without an IO board connected.
While lots of games do support the maple buss ports, very few games will allow you to boot without an io board connected.
looking quickly it looks like MAYBE only 2 games would allow this
-Heavy Metal Geomatrix
-Musapeys Choco Marker
no guarantee though as I haven't tested it myself.
