If you want to compress your own backup discs or existing ISOs down to the 50 MB range, you can use specialized tools. However, you must first "rip" the data (delete dummy updates and video files) using tools like . Once the ISO is lean, you can convert it to a CSO using a "level 9" compression ratio, which squeezes the game to its absolute smallest size. Tools like PSP ISO Compressor or the high-performance maxcso allow you to set compression levels (1–9).
Set to 1 to bypass occasional lag spikes during intense action sequences.

The technical "magic" behind this compression is a fascinating, albeit lossy, process. Achievers of the 50 MB target employ a ruthless toolkit. First, video files (FMVs - Full Motion Videos) are re-encoded to extremely low resolutions and bitrates, often stripping them of audio or leaving them heavily pixelated. Second, audio tracks are downsampled from high-fidelity stereo to low-bitrate mono. Third, textures—the visual skins of characters and environments—are downgraded and compressed. In the most extreme cases, developers "rip" (remove) extraneous content, such as multiple language packs, tutorial levels, or even entire game modes. The result is a playable but technically butchered version of the original. Cutscenes become blocky slideshows, music sounds tinny and compressed, and loading times may increase as the emulator struggles to decode the hyper-compressed assets.
