To play these archived files, your PSP must be running , such as Pro-C or ME. This removes the UMD requirement, allowing games to run directly from the Memory Stick. How to Install and Play:

If you're using a with internal storage, CSO is almost mandatory to fit more games. On a PC, the space savings may not be worth the minor CPU overhead unless you have many games. cso psp archive

If you are a PlayStation Portable (PSP) enthusiast, you’ve likely encountered the term . Short for Compressed ISO , a CSO file is a space-saving version of a standard PSP game disc image (ISO). While a standard ISO is a bit-for-bit digital copy of a UMD disc, a CSO uses lossless compression to shrink that data down, allowing you to fit more titles onto your memory stick.

| Format | Compression | Load Time Impact | Use Case | |--------|-------------|------------------|-----------| | ISO | None (raw) | Fastest (no decompression) | Original rips, emulators | | CSO | Yes (DEFLATE-like) | Slightly slower (decompress on the fly) | Saving space on PSP hardware or emulators | maxcso -o game

For instance, a 1.8GB game like God of War: Chains of Olympus can be reduced to around 1.2GB or less, while other games with more compressible data (like many RPGs) may see even greater savings.

This is a massive benefit for those using memory cards or limited storage space on their device or computer.

For archival purposes, several tools are used to "generate" or convert these files:
