I tried Super Mario Kart with PocketSNES fast, it works well, but the FPS slows down when there are many objects on screen (from a maximum of 45 fps to a minimum of 23 fps).
I set the audio output at 22050 kHz stereo and the Caanoo CPU at 540 MHz.
I Tried various games ROMs and the emulator (drPocketSNES 7.1.0) seems to run fine (just more slow respect an "original" Wiz)...
I used a Caanoo with firmware 1.6.0.
@ Fluiquid: de nada! It's a pleasure! :)
