PPSSPP - a fast and portable PSP emulator

Created by Henrik Rydgård

Additional code by many contributors, see the Credits screen

Originally released under the GPL 2.0 (and later) in November 2012

Official website: https://www.ppsspp.org/

No BIOS file required to play, PPSSPP is in many ways a "HLE" emulator.

Status

Code is a bit of a mess and it's not fully functional yet, I still need to implement some functions and add a upnp lib(really important for people with routers).

I did test it with some games(emulator <-> real psp with the server running locally) and it's looking good:

  • Worms Open Warfare: Ran just fine, I was able to play a whole match without problems
  • Monster Hunter Freedom Unite: Runs fine too. Gathering Hall and embarking on quests works
  • Dissidia Duodecim 012: Doesn't work. It requires some functions that I haven't implemented yet. Also, it uses a port < 1000 and thats reserved for admin apps on linux, running the emu as sudo "solves" it, but it's far from ideal.
  • Pacman World Rally: Works too.

Update (Kyhel) :
