How do I legitally transfer my PSP games to my PC?

[MMXZero2002]

Okay, I got the Power Stone Collection (USA ver.) game onto my PC and put it in the UMDImage subfolder of the emu. I can run the game and I see up to the screen where you select if you want to play Power Stone 1 or 2, however, after that, the screen just stays on a loading screen forever (or sometimes just a black screen). Is Power Stone Collection compatible with the emu? I am using the 64-bit version that is listed on the main site's Download section. I also tried the 32-bit version, but that froze on the load/create a save screen, which appears way before the game select screen (and for some reason the 32-bit emu doesn't have any text in the load/create save screen). I converted the game from my PSP via UMDGen and I converted it as an .ISO file. I didn't alter any options for the converting proccess and I didn't do the ppf patch or dummy search (since I have no idea what those do). Any help with this stuff would be greatly appreciated. I am really greatful for all the help everyone has given me so far.

Thanks.
