Here's why:
* Game Compatibility: The PSP had a different architecture and processor than the platforms Marvel vs. Capcom was designed for (like the PlayStation 2 or Arcade).
* Official Release: No official version of Marvel vs. Capcom was ever developed for the PSP.
If you want to play a fighting game on your PSP, you have a few options:
* Other Fighting Games: Search for other fighting games released for the PSP, like Tekken 6, Street Fighter Alpha 3 Max, or Blazblue: Calamity Trigger.
* PSP Emulation: If you're willing to explore emulation, you can try using a PSP emulator on your computer (like PPSSPP) and playing a PC version of Marvel vs. Capcom. However, this requires setting up the emulator and finding a compatible ROM, which may be illegal depending on your region.
It's important to note that playing games through emulation may require technical knowledge and potentially involve obtaining game files that could be illegal in your area.
