I'm trying to set up portal reloaded for speedrunning on linux and Livesplit autosplitter doesn't work in wine, even when I import the sar.asl file, so I searched for some other usable timers for linux (llanfair, flitter...) but none of them have an autosplitting feature but I have the sar.asl file so is there any way to run it so it works in flitter or llanfair?
One that people use commonly on the Linux side is Adrift, which can be found here: https://github.com/mlugg/adrift
If you have any questions, you can ask in the p2sr discord, since we are the main community that uses Adrift.
There are now boards and support for reloaded coop in our speedrunning plugin SAR! All you need to do is update to the latest pre-release (1.13.0pre1) and setup your splits the same way you would a single player run.
Best of luck on runs, and if you have any questions please ask them in our speedr
