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

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

ADHOC SUPPORT (by Igor Calabria)
|
|
================================
|
|
This is based on coldbird's code: http://code.google.com/p/aemu/

All credit goes to him!

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) :
|
|
---------------
|
|
* Now compiles on both Mac OSX and Windows. For more details on how to play and build
|
|
go to see there http://forums.ppsspp.org/showthread.php?tid=3595&pid=59241#pid59241
|
|
* Got it tested windows <-> mac osx <-> psp, it works
|
|
* Monster Hunter 3rd HD works too, as well as God Eater Burst.
