@EnnaComa @Sui @BowsacNoodle @Decayable @Formerly_Trucks @Morghur Almost fuckin got it, though it was a clusterfuck because I don't know what I'm doing and half the download links are dead.

(fuse2 might be libfuse2, try that if you get an error)

There's a version that includes meridian xl, but it always hung up for me, but it still gets you the base game + expansion pack
>extract d2launcher & res folder to the game directory
github.com/murkl/d2launcher/archive/refs/tags/4.1.1.tar.gz
>run d2launcher and apply the meridian xl patch
The game kind of runs at this point, but the rendering is jacked with part of the game cut off the display, thus
>in d2launcher, >settings>edit configuration>change -3dfx under d2args to -ddraw
I had the d2args line in there twice by default so I just deleted one.
Apparently you need something called sigma2 to play online, not sure if that's standard or if that'll be an additional step. I got everything running and can play single player, but it hangs when trying to join an online match. Creating an online game works though, so who knows what's next.
