D2GL is a Diablo 2 LoD Glide/DDraw to OpenGL wrapper that translates glide/ddraw calls to OpenGL calls. This makes D2 run better on modern hardware/OS and easier to switch between fullscreen and windowed modes, and resolves certain window and cursor-related issues. Additionally, it includes several libretro shaders for upscaling to higher resolutions, and allows for in-game text to be displayed in high-definition, D2DX's motion prediction, other QOL features.

Please don't just say it crashes. I can't do anything without additional information!
If you want to report bug or crash please include details about your system (OS, hardware), what you doing when crash occured, are other mods included (like plugy, basemod etc), is crashing on both wrappers (glide, ddraw).
Also run game.exe with -3dfx -log it will create d2gl.log and attach this along with diablo2's log file like this D2230410.txt. It helps investigation.
