Well, SDL is to some extent this advanced gaming API, its current implementation for Nokia 770/N800 is just poor. As for pixel doubling, a practical solution would be just to support 400x240 fullscreen resolution in SDL so that no extra hack would be required when porting each game or emulator in particular. N800 hardware probably makes it possible to set any resolution up to 800x480, with all this available using standard SDL API. Having support for both pixel doubled and normal graphics in the same game may be useful, but it will require extra efforts when porting games, while low resolution may already work out of the box without doing any tweaks to the sources. Let's try the simple solution first. The very first step would be to take Nokia 770 xserver and SDL sources and tweak them until setting 400x240 fullscreen resolution works transparently for any SDL applications. Anybody up to this task? Also it would be a good idea to benchmark SDL, identify maemo or ARM architecture related bottlenecks and try to fix them. Many older generation games worked perfectly on hardware way slower than Nokia 770. So Nokia 770 may be a good platform for mobile gaming if properly optimized (though I'm not sure about realtime games because of unsuitable controls). I could probably do these optimizations myself, but have quite a limited amount of free time available for free software development. _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
