you know, keyb, joystick and audio on the side of VGA gen on 16MHz is too much; its causing too much display distortion and not even got to audio yet; also, it means we are very limited .. but if we add another mcu as IO chip, then VGA can do its business best as it can, and the IO chip is suddenly half empty.. keyb and joy are trivial for it, and it could maybe pull off the avr-SID codebase as well for good audio, and still leave pins left over for hackability... maybe this is the way to go
