Damn, I was half-expecting something like that to be the case. Welp, hopefully somebody else ports multiplayer enabled versions.even if it did, tyrquake's network code was stripped from the core and it would need a bespoke server based on the core modified code since the iteration model is different from the standalone tyrquake.
not sure about prboom but I think the iteration model has changed too.. even if it didn't we don't have a way to enter settings such as server IP address or anything like that so even if it worked it would be unusable.
As RetroArch's builtin rollback based netplay is quite resource intensive so it's not likely to work well on the 3ds.
Still looking forward to the retroarch cores for singleplayer, but the lack of multiplayer is a bummer.
