Removing Update Files: PC tools like UMDGen can be used to manually strip out "UPDATE" folders or non-essential foreign language audio to further reduce a game's size.

: Highly compressed files require the PSP to decompress data "on the fly". This can lead to lag in demanding titles like Grand Theft Auto: Liberty City Stories God of War: Chains of Olympus Loading Times
: Compressed games often take longer to load assets compared to their uncompressed counterparts. Audio/Video Issues
: In extreme cases, high compression can cause cutscenes to skip or background music to stutter. Strategic Recommendations
