Multi-player fighting games on PPSSPP

[Squall]

I would like to see a way to play multi-player fighting games in the same screen.
Both players would use a gamepad, or player 1 would use the keyboard and player 2 a gamepad.

There are lots of fighting games, for instance:
BlazBlue: Calamity Trigger | Continuum Shift Extend
Tekken: Dark Resurrection | Tekken 6
Soul Calibur: Broken Destiny
Mortal Kombat: Unchained

I do not know if there are existing solutions for real hardware or if the PSP emulator present in PS3 has this feature.
PSP can be connected on a TV and it has a mini-USB port. Then if a controller could use the mini-USB port, I wonder if two players can play using the same TV and the same single PSP.

If no real solution exists, I have an idea.

The first step is the implementation of communication between two PPSSPP windows. VBA does it with GBA.
Of course, the Android version would use two Android devices, but the PC version needs a solution.

When someone want to play on PC with multi-player, they would start the game on the first PPSSPP window and go to the option that allows multiplayer without starting the communication.
Before the communication, the user press a key to save the state of first window and the second window would be open and would load the state. After this, they start a communication in both windows.
After the players choose the characters, they would press a key to hide the second window, disable the video and audio output of the second window and keep the controller inputs. Because two PPSSPP windows may be slow.
The fight would happen in the first window (and it can be full screen) while the second window would only have the CPU emulation with inputs and with dummy GPU.
To re-enable the second window, they only need to press that key again.

This would work only in games like Tekken that both players share the same perspective/point of view. On games that characters have different perspective/point of view, you need 2 of em.

Very cool this idea! It would be great if it worked! An emulation two PSPs on one screen to play Tekken! It would be very difficult to create that option in the emulator? Would be perfect! =)

At the moment we can only dream. But the reality is, it won't happen IMO. But I'm optimistic and hope for this to accur someday... Well before I die

[chaolan]

LOL. I think you're being a little dramatic ...
I believe that to do this procedure gives a small emulation mode within the LAN. Let's wait. I cheer a lot for it to work!

its a shame dead or alive isn't on psp..

to the topic starter, sorry for a very late comment @.@
this is already possible for JPCSP (a psp emulator as well) for quite some time now

1 PC running 2 emulator, 1 client 1 server, (actually 2 PC on 1 router also works)
all you need to do is add netclient/netserver on the .bat file of each emulator

so basically i think PPSSPP community can base of something out of this

so.. let's complete the multiplayer emulation before and after that, we'll see what henrik planed to do.. probably hook it to wifi or something... and maybe a feature like this

[gh0stx]

i really hope this multiplayer feature will be implemented in the future

Can't wait to try Gundam vs Gundam NEXT Plus in multiplayer.

Hue.

Yeah! That's it right there! But we all wish it were in PPSSPP emulator! Let's wait ... I'm sure the PPSSPP team will do that and better! =)

:RUN
echo Running Jpcsp 64bit...
"%JAVA_CMD%" -Xmx1024m -Xss2m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/windows-amd64 -jar bin/jpcsp.jar --netServerPortShift 100 %*
if ERRORLEVEL 1 goto PAUSE
goto END

in the .bat file of JPCSP the one in bold "makes" it possible to be a server

im not good with this so i got no idea what the stuff in there is all about xD

[DarkHaze]

Yup Exactly what we Thought Squall its entirely Possible and I would want to play Kingdom hearts BBS with someone to help in Multiplayer and God eater Burst let's make this thread Popular so Mr.Admin might look into it XD

well topic is on "off-topic" and i think there is another topic regarding xlink kai :o
but i for one think lan should be first before online capability, although ofc i want online better lol

Well I'd like Two PPSSPP in one screen it'd be much more easier...
