The short answer is no. Capcom never officially released an office port of Resident Evil 4 for the Sony PSP. While the game was famously ported to almost every other platform—including the GameCube, PS2, PC, Wii, and even mobile phones—the PSP was skipped.
When you see "Resident Evil 4 PSP" downloads online, they usually fall into one of three categories:
Fan-Made Mods: Developers in the community have created "fan ports" based on the Resident Evil 4: Mobile Edition (originally for iOS/Android), modified to run on PSP homebrew.
ISO Mods of Other Games: Some "RE4 PSP" files are actually heavily modded versions of games like Syphon Filter or Socom, with textures swapped to look like Leon S. Kennedy.
PPSSPP Redirects: Many "highly compressed" files are intended for the PPSSPP emulator on Android, but they are often just the mobile version of the game packaged as an ISO. Understanding "Highly Compressed" PSP Games
"Highly compressed" refers to reducing a game's file size (often from 1GB+ down to 100MB–500MB) by removing non-essential data.
CSO Format: The PSP uses a compressed ISO format called .CSO. This can save space on your Memory Stick by "stripping" dummy data.
Ripped Content: True "highly compressed" versions often remove high-quality cinematic cutscenes, music, or multiplayer files to save space.
The Risk: Be extremely cautious of files under 100MB claiming to be the full game. These are frequently "clickbait" files or may contain malware. How to Actually Play Resident Evil on PSP
