I mean, I connect my PSP to my WLAN router and can I play with another person connecting their PSP to their WLAN router?
I know it'd need a program, but I don't know if such thing exists.
I used a program like that to play Mario Kart Double Dash online a couple of years ago, but I don't know if the program, Pipewire if I'm correct, works with any console that can connect to each other throught LAN or AdHoc.
