I thought I'd see if I could play UQM on my N800, so I threw together some packages for it. It's a rather quick port, but it actually works suprisingly well, so I thought someone else might be interested too.
The game expects to find the content packages in /media/mmc2/uqm/content/packages/ (that's the internal mc) and the remixes will also work if placed in /media/mmc2/uqm/content/packages/addons/uqmremix/. (http://sc2.sourceforge.net/downloads.php)
