I think you're being confused by the fact that accelemymote gui is basically a toggle. I've never once had it fail to start up accelemymote and had no reports of it in the accelemymote thread. I wish you'd inquire instead of make statements like that. Feedback is very useful to devs, but it has to be seen... The best way to use the accelerometer would be to invoke the backend portion of accelemymote directly in a script that starts the emulator, and shuts it down when the emulator quits. This is what e.g. MAME does. I can help with that... PS When i type mupen64plus <the name of the rom file, I swear if anyone blindly types this out with the bracket and then posts about it I will end them>, it gives me an error. :P
