The primary goal of this hack is to add features to the original N64 version of Doom from Nightdive’s 2020 remaster.
This includes not only the extra levels, green blood, and medikit sprite variations from the 2020 version of the game but also a ton of cool quality-of-life features like the ability to save the game in the menu (the original game used a password system instead) and the ability to lock various controller bindings to specific game files.
