* YELLOW - emulate F7 key / virtual keyboard.
* BLUE and RETURN - emulate ESC key.
* EXIT, SOURCE, P+, P-, TV, POWER, CONTENT - trigger an immediate exit from ScummVM (bug?)
* Audio is delayed by up to one second. This is a TV software issue :/
* Do not use 3x scalers. They do not fit in the TV display's frame buffer and will cause graphical glitches.
