Single Status Update
I just published an article on Medium that explains how I managed to patch the Doom II executable in order to fix the Arch-Vile fire spawned at the wrong location bug using a hex editor. Some knowledge of assembly may be required to understand everything.
I started to write this article in July to describe how I did the patch for my Doom patcher tool. The article was 90% done, but then I got lazy and didn't touch it again until this week. :D
