I have been playing these games off and on yesterday paper mario worked perfectly, today it just opens, plays its theme and the screen stays black. Could it be a setting in the graphics menu that did this, i changed the grapics settings so i could play mario kart wii, got it working perfectly with no lag, I even recorded it. I tried to open ledgend of zelda, ocarina of time, It did the same thing paper mario did. then I opened super mario world it worked perfectly. confused about this i messed around in the graphics settings and changed them a bit, still nothing worked, i changed the backend. i cant seem to fix it myself.
