Hey I just went to my friends to UMD dump SSX on tour to my PSP but I just found out it takes up over a gig to keep it on there I do have a 4 gig but I cant start my PSP with it in and that could be a problem so can eneyone tell me how to make the thing smaller?

A simple fix would be to use an iso compressor... that will compress the iso while still leaving all the extras like movies and stuff. Using UMDgen you can actually edit everything, taking out movies and such and try and get the game to its bare bones for a lot of saved space.
