Wizard of Oz: Beyond the yellow brick road is unplayable

[Cap1ain]

I have tried everything and every ARM7 emulation setting but the game is completely unplayable and super slow, the graphics glitch all over the place and when you finally do manage to get into the game it’s just black. Also there’s no easy way to do anything because the movement of the character is tied to stylus movement on a trackball on the bottom screen and dsvita doesn’t have an option to link stylus trackball controls to the stick.
