Default [Q] Bluetooth controller w/ Emulators question

Sorry if this has been discussed to death, but I tried searching for a while and couldnt find any definitive, none hardware specific answers.

I am currently using a Galaxy Tab 8.9 and my Galaxy S3. I purchased A "Red Samurai" controller, it has been working fine with stock android games, but when I try to run SNES/NES/Genesis emulators, I am unable to keymap diagonals. I have tried SuperGNES, SNES9x, and a couple others with no luck. I remember about a decade or so back when I was messing around with emulators a similar problem was due to keyboard input and it couldn't regonize multiple commands at once. Does it stem from this? Has anyone come up with a work around? Any help is appreciated.
