san andreas stories is not possible on a umd
first of all, GTA SA required a dual layer disc
porting it to the psp would require so much watering down and stripping that the game would FAIL
I mean VCS already took 1.6 Gb pretty much filling up the UMD(dont know how much space is required for the UMD to work) and it didnt even have all the features from SA
so yeah SA equals no-go
