Hello, this is Sys, posting from another forum (DissidiaForums). I am posting today about some Networking problems involving Hamachi and PPSSPP that I have encountered with several of my online buddies over the course of a few days. If anyone else has encountered the same following issues as I have before, please chime in so we can resolve this together.

What I was trying to do over the last few days was basically to try to conduct a Group Battle in Duodecim 012 with more than 3 people. However, we have had very limited success with this because whenever one of us hosted a room with 3+ people, the farthest we've gone was the "Preparing for Online Battle..." screen and nothing more than that (Not counting that one exception where we were ACTUALLY able to get 3 different people to participate in a match, one of them being a spectator). Here are our PPSSPP Networking Settings:

Enable networking/WLAN = ENABLED
Change PRO ad hoc server IP address = one of our IPs in our party (we tried Coldbird but no one wanted to try DMZ-ing)
Enable built-in PRO ad hoc server = DISABLED
Change MAC address = UNCHANGED

Various errors encountered:

- Socket error when connecting to XX.X.XXX.XXX IP address
- Packet loss
- frame-by-frame lag in the miracle that 4 of us are able to proceed to the "Prepare for Online Battle" screen at once, cannot proceed to Party A/Party B screen

It is very frustrating that these redundant Networking problems are occurring with PPSSPP and Hamachi in the first place, and so, here's what we tried so far:

- hosting with several different IP addresses amongst our group (everyone left the Networking settings unchanged, making sure they're all the same otherwise)
- getting the host to enable "Enable built-in PRO ad hoc server" while everyone else disables this option

(Obviously, none of the above got us to play even a single match in a party of more than 3+ people)

I've started reading today about the implications of TCP and UPnP in the "Status Update on Coldbird / PRO Online" thread on coldbird.net. Have no idea how any of this connects to this issue since I have close-to-zero technical networking knowledge, so any help on this would be greatly appreciated.

QUICK-NOTE: We all otherwise have no problems playing 1v1 matches. They play perfectly with very few random crashes.

Try using this Win32 build https://www.dropbox.com/s/xdgwhfnwt8fuu3...s.zip?dl=0
(based on http://github.com/ANR2MERefork/ppsspp with a fix to some of the crash issue, but there is still one crash issue remaining)



PS: There seems to be a crash issue at Jit.cpp (at line: ((void (*)())enterDispatcher)(); ) when i started the multiplayer battle with 4 players (running 4 instances of the attached PPSSPP on the same computer), 2 of the players always crashed at the same location, while the other 2 are okay.

Edit: There is also an issue where Adhoc MatchingHandler MipsCall/Callback failed to return within 250ms while it usually only takes a few milliseconds making the game stuck unable to communicate properly, could be a race-condition occurred.
