Can I use mods on PPSSPP?

[azelius3]

Hello! This is my first thread so it's unusual I'd start asking questions right off the bat, but there's one important question I have.

Is it possible to mod my game using an emulator? When I used to actually own a PSP, I had a modded version of GTA:VCS which was really fun to mess around with and so it would be really neat if I could mod my emulated game.

Thanks in advance!
