Hacking Is there any plugin that can change the aspect ratio?

[Sleet]

Some games when ported to PSP are stretched to fill in the entire screen. I want a plugin that can change the resolution to the original 4:3.

Could you give more details?

Ported how? The PSP can run various types of software and this may or may not be possible depending on what the games are and how exactly they're run (on a technical level). Official games, POPS, homebrew, emulators, blah blah blah.

I'm talking mostly about homebrew ports of old PC games. Some are stretched without the option to set them to their original aspect ratio.
