Emulation on PSP fat

Is it possible to put emulators on a hacked PSP 1000? I just read that old PSP have a lot of trouble with these.

yeah its possible if (1) your running a low firmware (2) used a pandora to either roll back to the original firmware or have installed a custom firmware.then check here. https://www.romulation.org/forum/index.php?topic=5378.0
