I meant to this add but hit SEND too quickly:  If I was doing this I'd look
into having the PIC control the boost switcher directly.  There are various
PICs available with built in comparators, and some of them even have
absolute voltage references too.  Tomas never said what the computing
requirements of his game are, but all might be doable using a single PIC for
the game logic and the power supply controller.
