Getting SOCOM: U.S. Navy SEALs Fireteam Bravo 3 to run in a "highly compressed" format on your PSP is a common way to save space on your Memory Stick. The original game size is roughly 1.2 GB, but it can be reduced significantly—sometimes to as low as 400 MB–600 MB—depending on the compression level and whether game data like videos or music are stripped out. How to Compress the Game
If you have the full ISO file, you can compress it yourself into a CSO (Compressed ISO) format using tools like PSP ISO Compressor or UMDGen.
Download a Compressor: Use a tool like UMDGen to open your ISO. Save as CSO: In the "Save" options, select .CSO. Compression Level: You can choose levels 1 through 9.
Level 9 offers the highest compression but may cause slower loading times or occasional "stuttering" during gameplay.
Level 5–7 is usually the "sweet spot" for maintaining performance while saving space. Performance Tips for Compressed Versions
