Well sweet. If Allegro is ported then there may be a fair chance that ZC could run well in the N9 phones. To actually get access to the code before it goes Open Source you will have to talk to a ZC Developer. Also I know almost nothing about Allegro and nothing about how ZC is built.
Since you posted this I am wondering how difficult it would be to port ZC/Allegro to Android with Android NDK. I suppose with a large touch screen(I have a 4.7inch screen with 720p display) most quests could be playable with a touch screen.
