Hey, so i tryed to play Systemlink Games with two other non-RGH Consoles, but i cantsee other Games and they cant join my games. We have the same TUs, the same Games (mediaid), we are in the same ip-subnet and i have LINK disabled. The Only Game where i see a game is HAWKs but when i try to join there is only a timeout Message. Can someone help with that?
