Then, SDL keyboard has no Numpad at all. And I cannot switch to Direct input mode, because I am unable to press both mouse buttons (because of touchscreen). It would be nice to add separate controls for Android (#ifdef ANDORID ... #endif)
I've successfully compiled UniPCemu for Android with libSDL by Pelya, but it is unusable due to controls designed for PSP, etc. This implementation of SDL uses standard PC keyboard. I think, for example, arrows should work as arrows and Enter as Enter.
