PPSSPP to Vita Multiplayer?

[Wofford16]

Is it possible to play PSP games multi-player through PPSSPP and CFW + Adrenaline on Vita? I got Peace Walker on Vita and I wanna play it with my brother but don't wanna buy another Vita.

It's possible on PC/Mac when you're connected to the same network with your PSP/Vita by using PPSSPP built-in AdhocServer, you can find more info at PPSSPP wiki https://github.com/hrydgard/ppsspp/wiki/...ith-PPSSPP

Sorry, I should have specified. Is there any way to do this on Android? That's the only way we can for a while.

Depends on the game whether they use ports under 1024 or not, for games that use port under 1024 it's not possible when using the same network/LAN, due to Android restriction not allowing to bind/listen on ports under 1024.

Might be possible over the internet (if your ISP allow port-forwarding on ports under 1024) by enabling "UPnP use original port" setting on PPSSPP and both device need to use different public IP (ie. different ISP), but not guaranteed to work.

However, if the game didn't use any ports under 1024, it should works, just need to set Port Offset to 0 so PPSSPP will use the same ports used on real PSP.
Not sure which ports used by Peace Walker tho, you can test it yourself.
Usually on PPSSPP you will see red message on screen saying "Failed to bind port xxx" when PPSSPP can't use that xxx port number, if you didn't see these messages it might works (unless there are external factor such as firewall or port-forwarding issue)

Okay, thank you so much. I'll give it a try and see what happens.
