Is anyone familiar with PPSSPP multiplayer? I see there are two options, ad hoc and online and have a few questions. I read that online multiplayer is really just tricks around ad hoc mode, and it requires port opening on the router to work. Does that mean that it won’t even work if I’m on cellular data?

If I’m playing with someone on the same WiFi in ad hoc mode, both on Android phones, will it work as is or are there also ports to open? I don’t even know what kind of firewall Android sets up. Thanks for your answers, just want to play with friends.
