I just remembered something about the CoCo system that might be fun:
The basic joystick controllers were "free floating" so to speak, ie, they didn't jump back to the center position when you let go of them. I noticed that a lot of programmers of the time (including myself!) used that as an advantage, like Dave Edson's "Catch'Em", which would be difficult to play if the stick snapped back. It occurs to me that the Wiimote has such a quality too, and this could be emulated. I've never seen an emu for this computer that uses that properly (I've seen joystick functions mapped to the arrow keys, but that's a bad bad joke).
Anyway, thought I'd say. I've seen a few CoCo emus online now that let you mess with the source code, so if anyone has some time, have a look! Might be fun!
