It runs now! And of course much better performance, thank you for your help! Audio is a bit crunchy and crackly now which is annoying but a big step forward from black screen.

msbuild can be installed on arch linux with the mono-msbuild package

Msbuild doesn't seem to work for me, so instead I just used xbuild and it worked flawlessly

Could someone be kind enough to help me with using this with other Renderers than OpenGL on Arch Linux? I updated the Kickstarter and ran this Script, but /gldevice:Vulkan freezes right after starting the game, something about VK_DEVICE_LOST. Trying to start with /gldevice:D3D11 complains about no valid driver being found

Edit: Solved it by installing libdxvk and lib32-libdxvk from AUR. And also vkd3d and lib32-vkd3d from Extra and Multilib Repo

This works fine for Terraria but not as well for tModLoader.

I tried using this for tModLoader, but it seems they use a modified version of FNA. As a result, using the FNA.dll built by this script crashes the game.

You can replace the libraries without any issues though. Run the script in an empty folder. Once the libraries are built (specifically, libFNA3D.so.0, libFAudio.so.0, libSDL2-2.0.so.0, and libtheorafile.so, saved in /lib64), copy them to /tModLoader/Libraries/Native/Linux/. It won't crash if you don't replace FNA.dll. However, I’m not sure if tModLoader's libraries are outdated, so replacing them might not have any effect.

fnalibs.tar.bz2 do not seem to be part of that flibitijibibo archive link anymore, but rather this link:
https://github.com/FNA-XNA/fnalibs-dailies/actions

this should probably be updated
