Emulator: SNES9x

The reason I'm using the back buttons as the up and down inputs is because my fat fingers sometimes cause me to press 2 dpad buttons at once. This causes a bit of annoyance as sometimes jabs won't register and instead Mac will just do a body punch, so I just decided to change it. It makes for a bit of confusion and disorientation at first but after a while I got used to it.
