Yeah, you have to put Halo 2 on your hard drive.
Tut here...
And to get trainers,
Get the Evox rar, then extract it to your decktop. Make a folder called EvoX and move everything in there, make sure that allm the files arent in any subfolders, so once you go into the EvoX folder you see evoxdash.xbe, the ini, etc.
Rename evoxdash.xbe to default.xbe.
Download the Halo 2 DEVELOPERS TRAINER (not camera one) and put the etm in your trainers folder
FTP the EvoX folder to your Applications folder
Press start on Applications on UnleashX, and press refresh list
There will be a new application, Not called EvolutionX, but *****X (i forgot what its called, but it ends in X)
RUn that application
Go to settings, then scroll all the way down to TRS or something similar to that in the Misc category, and set that to Normal. Save and Exit
Go to trainers, and enable everything in the halo 2 Developers trainer, then save and exit.
Go to games, and run halo 2 (make sure your AU is disabled!)
When halo 2 has run, load up any map.
When the map has loaded, Hold the right thumbstick down and press any of the 4 directional pad buttons. If the camera prespective changes, you have done it right.
