DOOM-CRT

This is the original DOOM shareware version, running on Windows, with my CRT emulation filter applied.

If you want a good, solid version of DOOM for playing the game properly, this is probably not the version you want - there are many better ports which have fixed bugs and added features and (maybe most importantly) are better tested than this (this was just a fun weekend project for me).

But if you just want to give it a quick go and see my CRT shader in action, check it out!

The source code is available here (and it is super easy to build)
