In the context of PSP gaming, "Highly Compressed" refers to a process where the original ISO file is shrunk down significantly using compression formats like .cso (Compressed ISO) or .dax.

| Method | Realistic Saving | Result | |--------|------------------|--------| | CSO (standard PSP compression) | 20–30% | Working, load times longer | | Dummy file removal | 0–5% | No dummy files in this game | | Audio downsampling | 10–15% | Lower quality, sometimes glitchy | | Video removal | 30–35% | No story cutscenes, broken intro | | LBA (Logical Block Addressing) repack | 0% | Risky, often corrupts saves | In the context of PSP gaming, "Highly Compressed"
