If it was just a matter of recompiliing, then I'd have a shot at recompiling some of my things for it but I can see there being many potential problems if they just do a quick job. Silly things, like the button assignments changing (so that, say, button 1 is UP on the GP2X but DOWN on the Wiz etc.), sound frequencies breaking like they did with the F-200's, etc. They seem to be sticking to most things - if they'd changed the resolution, for example, you could create a lot of work for the smaller projects or the SDL libraries in order to cope. There's some things that can't be helped, like the video RAM, video decoder firmware, sound buffer etc. will probably change location so anything that's hard-coded those values will need more than a recompile - anything that uses the mmuhack module, for instance, will need an updated version of some primitive code removal to remove references to it.
