I did some testing with a real hardware and I can confirm Marc's findings:

kbhit() also reacts to joystick movement which shouldn't happen in my 
opinion.

Pressing repeatable (and fast) one of these keys appear as joystick 
movement: Z, A, W, R, Y, I, P, £, *, control, D, G, J, L, return, B, M, 
dot, esc, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, home, and del. In other words, 
nearly all key presses are detected as joystick movement.
