Is it possible to adhoc play with Gundam Seed Rengo vs Zaft(ULJM05238)?

[JAPAN]

I attempted ad hoc play of this game with a friend, but I get an error on the lobby screen. Can you tell me how to adhoc play in this game?

The version of PPSSPP used the latest 1.6.3.

Well, why are you asking if you're the only person that tested it and have the answer already.
Unless you only tried online which sucks and would often not work through a lot of problems that are unrelated to emulation itself, from your connections latency(not related to "speed" of download/upload) to firewalls and closed ports.

The only good test to know if adhoc of some game works or not in ppsspp is to play on real proper LAN aka 2 or more pc's connected together, eventually using a custom build like mine which allows to play multiply instances of ppsspp on same pc without messing too much with other adhoc code.

If everything fails, you can always try jpcsp as well since it's said to have more complete adhoc emulation and more games might work with it althrough with low quality and much higher system requirements.
