I play a Doom romhack by Muhgaw!
If you want to play it, you're going to have to ask him for it:

Killer hotdogs, and fire breathing whiners, and glitched save features, oh my!
Edit: I've contacted the creator and he fixed the save bug. But considering the patch would effect my progress, I may just go without and try to find the quicksave key.
