It doesn't matter to me. Just trying to figure out what the exact process is to get it to work. I was able to get Firestorm working using ddraw and TSPatch for one install attempt, but haven't been able to get both to work again since then. Like it's not reproducible for me.
What's the exact procedure for installing it? Because between setting placing the ddraw files , using TSPatch with ddraw, using ddraw with patch 1.03, Compatibility mode (which i saw you noted can't be set with ddraw files), running as admin, etc.., I haven't been able to get it to work consistently.
Also as a sidenote, my environment is Windows 10 Pro x64 v2004
