Pretty much all of which I have connected to my 42" TV, excluding the handhelds of course.
Are you using TTMenu or YSMENU? On TTMenu on the top screen it lists in this order:
Name:
Size
SaveTIme:
GameCode:
The Game Code is the Game ID.
I have YSMENU on my TT but it only works with Moonshell 2 for some reason. WHen I try to launch it directly it does nothing.
