I created a discord community. Everyone can join and play some PSP, PS2, Citra, online adhoc games with emulators and get to know people. We use Radmin usually. I created all the necessary tutorials. You don't need to open any ports. I've played Killzone liberation co-op with some guys. It was very smooth. If you interested join we can try many games https://discord.gg/Ntv3s58GBt
