One of the coolest things about RetroArch is its simple implementation of netplay across a variety of emulators – at least, in theory. When it works, it’s great, but it can be pretty fiddly to get to that point. Luckily, the devs have put out an array of fixes and improvements in its latest update, and there are more on the way.
“Netplay has received plenty of improvements thanks to the efforts of Cthulhu,” the devs explain in the 1.9.14 update notes. “We have a lot more prepared for the next version, so consider this a prelude to the main event.” The current round of improvements include a variety of quality of life improvements and stability fixes, but “for the next version, we will finally address the relay MITM server issues”.
RetroArch’s MITM (man in the middle) server is intended to make connecting to other players more convenient, as it routes netplay traffic through a central relay. That prevents you from having to set up port forwarding or a VPN to connect with friends, but even the relay server has proven a bit fiddly in the past, so it’s good to see improvements on the way.
