Warioware twisted comes with a spin sensor which is the only way to control the game so the game cant work without it.
Maybe you should know what you're talking about before you open your mouth.
The patch is to replace the spin sensor with button controls, so you can emulate Warioware Twisted.
Audi, I've found that a lot of gpSP roms don't work simply because they're unzipped, try zipping the roms to a .zip format, and try again.
