PS1 emu for psp?

It's Sony's emulator and it's already embedded in the firmware.
When you get a PS1 game from PSN it is ran using that emulator.

If you want to convert your games you need an app like PSX2PSP and a custom firmware on your PSP.

You may want to install popsloader, since most games work better using older versions of the emulator.

Hey, what's up?

Shendo and Zieg beat me to it and I really don't have anything to add.

There was an actual PS1 homebrew emulator released but it became obsolete when Sony released a new firmware with PS1 backwards compatibility built in.
