i don't have time to really format this or anything, but i'll just paste a discord message i sent to someone. might fix it up after i get off work.
make sure you are on kernel 4.18.20 or below. (much easier than fixing and compiling wine for newer kernels)
next install wine. winehq.com probably has a tutorial if you need it.
run piry.exe ( https://piry.plutonium.pw/piry.exe ) in the directory you want the game. (open terminal in folder, and run wine ./piry.exe)
then download plutonium.exe (http://cdn.plutonium.pw/updater/plutonium.exe) and throw in the folder and run wine ./plutonium.exe -update-only
then grab the files from https://github.com/xerxes-at/T6ServerConfigs
place the .cfg files in your ./t6r/data/ folder and edit to your liking.
place the .bat files in your game folder and edit to your liking (including grabbing a key from https://platform.plutonium.pw/serverkeys to put in the .bat)
still in the folder in your terminal, run wineconsole <name-of-file>.bat and hopefully the server launches.
