edit: actually that one's pretty advanced isn't it? the only games i've tried with scummvm are BASS & kyrandia. but still, as it's a scumm game, i'd guess that doing a complete conversion is mad.
I don't get it, you said: "would love to see this on the Gp2x but can it be done?".
And if you knew that it ran on ScummVM (on the GP2X) wasn't that your answer?
