This program is used to convert PSP games from ISO-CSO or CSO-ISO to help game speed and size and also for games that don't run on your PSP running CFW this will fix it.
1. Run PSP ISO Compressor 1.4.exe and accept all defaults to install
2. Now open PSP ISO Compressor 1.4 and you will be at the main menu.
3. Choose the input file (source file) The game you have.
4. Choose the output file (destination file) the new file you created.
5. Choose what compression ISO to CSO will make it smaller (more compressed) CSO to ISO will create a larger file( less compressed)
An ISO file is less compressed so if you are running a CSO game that is choppy try converting to CSO.
The compression levels are marked 9-Best Compression 1- worse compression. What I suggest is when converting a file always start with level 1 if you have problems work your way up.

I created this document only for the most basic info see there website for more info.
