Fixed the missing sprites bug and games with a status bar on the bottom. Super Mario 3, Tiny Toon Adventures, Marble Madness, Kirby´s Adventure and Battletoads are playable. (Tiny Toons doesn´t quite put the status bar in the right place, but it´s not too far off.)
Fixed 4-screen mirroring (Gauntlet)
Also added mapper 34 support (Deadly Towers)
Dragon Warrior 3 + 4 still won´t start, Zelda II and Crystalis still have problems.
