The heaviest parts of Crisis Core are its stunning Full Motion Videos (FMVs) and orchestrated soundtrack. Extreme compression algorithms heavily compress these audio files into lower bitrates or downsample the video resolution. In extreme cases, the video files are removed entirely, replaced with blank files to trick the game engine. System Requirements for Emulation
Navigate to the folder where you extracted the .iso or .cso file. Click on the Crisis Core game icon to start playing. Best PPSSPP Settings for Smooth Performance
In extreme compression cases (under 400 MB), high-definition game cinematics or audio tracks may be slightly compressed to save space. Technical Prerequisites
The original ISO is large. A compressed version allows you to keep the game on a 2GB or 4GB Memory Stick Duo alongside other games Source.
