Hacking older Maemo diablo games to work on n900 is not the way to go. It will probably just make proper ports more unlikely since the momentum is gone and people will mistakenly associate the proper version with these hacks.

Anyways, how well does it work? I made an optified version of openredalert with playability fixes, but it's way too unstable for a release. It randomly fails to start and I've managed to load a campaign mission only once, but skirmish seems solid if nobody uses tesla coils. Openredalert is a fork of freera/freecnc so I'm not too positive about freera working that much better.
