i tried fun run on cm9 and it works perfect no crashing

 

Yes but he said he wanted a working camera. Cm9 does not have a fully working camera yet.

 

Not everything is working yet, but significant strides have been made recently. The camera on CM9 is partially working, but you still cannot take pictures with it unless you are in panorama mode I believe. Also camera switching is glitchy, but since the camera now connects, it is only a matter of time until CM9 works enough to be usable for you. Then, it should be easy to port those camera fixes to CM10 and we'll really have the ball rolling. I am going to test this on MTDEV CM7. A lot of fixes have came in between those six months between the last classic MIUI release and MTDEV CM7's most recent update. It works for me on MTDEV CM7 just fine.. If that does not work, try clearing the cache and dalvik for MIUI. If that doesn't work, and you really need games to work, try upgrading to MTDEV CM7. If you miss MIUI, you could always get a MIUI theme and install MiHome from the Play Store.

 

i didn't answer that part of his question because there isn't a fully functioning rom above 2.2. i was just stating that the game works on the phone.

 

CM7(android 2.3) is fully functional except hdmi. And hdmi doesnt mess with the daily use of the phone. So it can be called fully functional.
