Hi Julien - Version 1.6 works on my Samsung Moment with the retail pak0.pak from Quake 2. Performance is in the 5 - 9 Fps range. Not acceptable, but not a bad start either. It's 20 fps if I go outside on the first level and look at a wall though!
The sensors work good for control. And I'm using the Enter key on the Moment's keyboard to shoot. Sound works too, but the 2nd time I ran it I had no sound until I walked into the 1st room where you hear some radio comm traffic. Then all the sounds came back. (It was like it was taking a while to load the files.)
I can use the Moment's Optical Mouse to navigate the Quake 2 menu, and can click on Quit, Options, but not Video.
Keep up the good work!
