Solved Diablo 2: Halt error location line #1110 Expression unrecorveable intenral error 6fe218d5

The launcher merely runs the game without you having to create a shortcut and add all those parameters manually, it doesn't change the game if you are using the default launch options. Are you having the same issue when you create a game as well or only when joining one? What other 3rd party tools are you using (such as maphack or any other tools) and what are your selected launcher settings?
You can also create a shortcut for the Game.exe inside of your game directory or simply run the other desktop shortcut that does exactly that.
The game didn't change since the last time you played but your setup or configuration most likely did change and that's probably the culprit. Also, let us know what OS are you using W10/W11, etc.

 

So most likely the BH + DDRAW combination is what's causing the error for you and that's probably because of another installed software you have in your computer that causes the conflict. Try the BH + Glide Wrapper (3dfx) combination and if you're still getting the same error then replace BH with Sting maphack and see if you're getting the error still.

PS: What's your friend's account name?

 

The UNHANLED EXCEPTION (c0000000d) error with Glide Wrapper is harmless and has been addressed here, you can thank Microsoft for that as one of their older windows updates messed up multiple oldschool games not just Diablo but there's an easy fix to make that message go away upon closing the game. As for the pitch black screen, you are probably missing proper configuration and need to run D2VidTst.exe and select 3DFX Glide instead as your current configuration was set for DDraw. Have in mind all these are 3rd party tools for Diablo II and they may cause issues sometime on modern operating systems and various PC configurations due to multiple factors such as various installed software, multiple installed diablo clients over time that have been improperly removed, etc.

Glad to hear it's working fine with the Sting maphack, you're very welcome. Do you remember if you were using BH or Sting the last time you played here?
