i have a problem, i tried to download crash mind over mutant iso (by my brother's request) and they have multiple files, like 3 zip files. i have downloaded only 1 file i'm still waiting to complete the other 2 files. when i try to play it with the 1 file downloaded, after i pressed x and the psp logo shows up, there's only a black screen. is this normal due to the uncomplete file or does it mean it's uncompatible with my psp? my psp is on 5.00 M33 on HEN btw. the file size is 1.5 gb though.
