I have an idea for a game where the game plays a tone, then you must match the tone with your voice. I haven't seen the mic used anywhere (unless it has, in which case please link me) and i think this could be quite fun.
Technically, it should be possible since the microphone has been implemented
Not the case for USB-OTG on the other hand... (they are working on an easy way to use the latest linux kernels, maybe this should fix this)
That means that for now, we will be stuck using the built-in microphone.
I think a port of Performous
for GCW0 is possible. (SDL2 as a dependency)
That reminds me...
StepMania has not been ported to this handled yet !
