We must be objective. The mod is not perfect. Enemy AI is dumber, some voice lines are missing, and the final helicopter mission glitches frequently. Also, there is no online multiplayer. You are here for the campaign and ad-hoc splitscreen only.

But for the price ($0, if you own the original UMD legally per modding laws) and the engineering behind it, these flaws are negligible.

This is likely what you are looking for. A developer (Un-G) created a homebrew game that brings Modern Warfare weapons, mechanics, and maps to the PSP. It is often labeled as "COD: MW3 PSP."

A PSP ISO for "Call of Duty: Modern Warfare" is unlikely to be better than playing an official release on supported hardware. Legal risks, variable quality of fan-made ports, and security concerns make official options generally preferable.

Call of Duty: Modern Warfare on PSP

The PSP version of "Call of Duty: Modern Warfare" was released in 2009, titled "Call of Duty: Modern Warfare - Roads to Victory" in some regions, but commonly referred to as "Call of Duty: Modern Warfare" on PSP. This game is a handheld adaptation of the critically acclaimed first-person shooter "Call of Duty: Modern Warfare 2," but it does not directly translate the full experience of the console or PC versions. Instead, it offers a unique campaign and multiplayer experience tailored for the PSP.

Enable the 60 FPS patch (available via the PPSSPP cheat database). The original PSP ran this mod at 20-30 FPS. With the patch on a Snapdragon 8 Gen 2 or a PC, you get a locked 60 FPS Call of Duty 4 experience on a 6-inch screen. That is undeniably better than the original console's 30 FPS cap.

For some fans, running Call of Duty: Modern Warfare as a PSP ISO—either on original hardware, a modded PSP, or via emulation—promises portability and nostalgia. But does it actually give a better experience than modern platforms? This feature examines graphics, performance, controls, legality, preservation, and user experience to help readers decide.

The homebrew mod can lag on original PSP hardware because it pushes the system limits. Here is how to make it run smoothly:

For PSP Hardware:

  • Memory Stick Speedup: In the Recovery Menu (Hold R while turning on PSP), enable "Memory Stick Speedup" to reduce texture loading times.

    • For PPSSPP Emulator (Android/PC):

    Let’s rank the Call of Duty portable experiences:

    Why the ISO is better:

    The catch: No, you cannot play the "All Ghillied Up" sniper mission. No, you cannot fight Zachaev on a bridge. The PSP hardware simply cannot render the Call of Duty 4 scripted events. But for multiplayer deathmatch on the bus? This modded ISO is a miracle.
