searched around but couldn't find this in other threads
i stumbled upon this on engadget when someone ported this wii emulator on their PSP. Currently playing it on my PC and even got two wiimotes+nunchuks. It works with my PS3 controller but the tilt is very awkward. The wiimotes work perfectly. I referred to the bluetooth compatibility wiki and got a MSI usb-bt from memX. I play it full screen at low-res and almost all of the more popular games run fine. Really shows how crappy my low-end video card is haha.
Anyways, try it out at
