I tried seeking help on Reddit and even on the Lutris Discord, but I still have a problem and can't play this game. I attempted to install the game using the Lutris script, but it's simply not working, and Lutris doesn't recognize the diabdat.mpq file. I also tried installing it manually based on some suggestions from Reddit, but when I launch the game, I only see a black screen and hear the music. I experimented with various Wine versions, but I haven't had any luck so far.
I managed to launch the game and see something with Proton 7.0 but its unplayable. I started to see something with DXVK off
In my experiemce The Hell 2 has a visual glitch in Linux during the opening menus where they are all black. Judging from your screenshot and report of hearing audio you might be seeing the same thing - but in that case you mighy already be to the point where the game is playable.
Despite the black screen try interacting with the buttons with the mouse? Does the screen redraw itself in the vicinity of the mouse as you move it? If so, try to navigate the menu to start a new game.
Lol! I managed to start the game, and it seems that everything works fine. However, the screen does not redraw itself, unfortunately. I was only able to start a new game by pressing the arrow keys and enter. But, of course, I can't create a proper character like this..
