Edit: A new way to play play multiplayer on one PC (support 4 PPSSPP)
http://forums.ppsspp.org/showthread.php?tid=16972
you need adhoclocal
adhoclocal is written by Bigpet https://github.com/hrydgard/ppsspp/pull/7276
downloads:
ppsspp-v1.1.1-62-adhoclocal-chatSimple.7z: http://www.545c.com/file/125865817
PPSSPP-v1.1.1-62-chatSimple.7z: http://www.545c.com/file/125865820
PPSSPP-v1.0.1-2668-adhoclocal-chatSimple.zip: http://www.545c.com/file/118257344
Bigpet: this is obviously just a hack for now to be able to test networking without needing two PCs or a VM, especially because of the inelegantly hackish global localIP value.
onelight:
1. I add simple chat support
2. after PPSSPP-v1.0.1-832-adhoclocal-chatSimple, I try do some improve, it may help play adhoclocal or play online.
3. after PPSSPP-v1.0.1-2668-adhoclocal-chatSimple, fixed Gundam VS Gundam Next Plus, you can using it to play on one PC or play online.
Warning: adhoclocal doesn't working on windows XP
First, you should run 2 PPSSPP-adhoclocal from different folder.
for settings:
Note:
1. different PPSSPP-adhoclocal should have different bing address (127.0.0.2, 127.0.0.3, 127.0.0.4 etc)
2. all PPSSPPs using local pro AdhocServer IP (127.XXX.XXX.XXX)
you can also try using an original PPSSPP with one PPSSPP-adhoclocal
Then, just run you game and try to play.

About controls two PPSSPP:
If you have only one gamepad try this settings
the focused ppsspp only using keyboard, other ppsspp only using gamepad
If you want using 2 gamepads setting like this:
note:
1. no all game adhoc will work even it working on 2 PCs
2. you should enable built-in PRO Adhoc Server for one of PPSSPP-v1.0.1-832-adhoclocal-chatSimple or using adhocserver.exe if you using older adhoclocal builds.
3.If ppsspp-adhoclocal with ppsspp-adhoclocal not work, try ppsspp-adhoclocal with ppsspp (noadhoclocal) or ppsspp-adhoclocal with JPCSP.
5.If you get 'Socket error (10048) when connecting to 127.0.0.1/127.0.0.1:27312', try change pro AdhocServer IP address to another local IP (et. 127.0.0.5)
settings for play adhoclocal on one PC (for older builds)
I am using adhocserver.exe, disable built-in PRO Adhoc Server for all PPSSPP
download AdhocServer.exe http://www.sn9.us/file/92865164
OR
connect 4 (or more) PPSSPP on one PC also work
PPSSPP X4 (cant start hunting, ppsspp-adhoclocal with ppsspp-noadhoclocal can start hunting )
the 3rd PPSSPP using bing address 127.0.0.4 the 4th PPSSPP using 127.0.0.5

Just did some testing: http://report.ppsspp.org/logs/version/v0.9.9.1-1405-adhoclocal
Interesting findings, all the games that have problems with PPSSPP's Adhoc return these two values:
__KernelStopThread: thread xxx does not exist
sceKernelCreateThread(name=AdhocThread): unsupported options parameter 00001000

01-09-2015, 01:30 AM (This post was last modified: 02-08-2015 04:01 AM by onelight.)

Also can connect PPSSPP adhoclocal with PPSSPP and PPSSPP adhoclocal with JPCSP
If 2 PPSSPP adhoclocal not work, you can try PPSSPP adhoclocal with PPSSPP or PPSSPP adhoclocal with JPCSP

Tekken 6 works!

And.. what's with this socket error when connecting, it was that error at the beginning, than it worked fine and now again, now it's error (10048) ?? Any tips for that ??

I don't know what am I doing wrong, but it doesn't work for me from instruction. So I found it working when at least one window has Ad-hoc server enabled. ^^
Also there already working Wipeout Pulse and Fat Princess. (:
But for Soul Calibur, Tekken 6 and Metal Slug vmware is now working better I think. Or maybe there is something wrong and I should somehow create local network.. T.T

And Soul Calibur works just fine, i'm using 1 localadhoc and 1 normal ppsspp btw.

I tryed PPSSPP adhoclocal with PPSSPP (noadhoclocal)
but not connecting, displayed 'Socket error (10065) when connecting to 127.0.0.1/127.0.0.1:27312' in Yu-Gi-Oh! Tag Force 6 and tag force special.
What's wrong?

Yu-Gi-Oh! Tag Force 6 and tag force special working on 2 PC. It doesn't need play multiplayer on one PC

I'm getting that error sometimes, usually, disconnecting from internet solves it for me.

- yep!!! Finaly get it worked! I read your last post and tried again with:
1. Disabling all internet stuff. [Airplane mode, etc..]
2. In both of ppsspp changed properties to run from an administrator.
After this security window appeared asking me something about network and after this there were no errors, no need of adhoc server, Tekken 6 is damn beauty and smooth
EDIT:
- noticed that in non adhoc-local I turned on Ad-Hoc server. For me it works with it.

- Cars
- Crash Tag Team Racing
- Metal Slug XX
- Micro Machines V4
- Midnight Club 3

- Soul Calibur (!!!)
- Tekken 6 (!!!)
- Wipeout Pulse
- Wipeout Pure
- World Rally Championship
