Boom-compatible source port required to play! An attempt to build what might have been Version 0.5 of Freedoom with the source code that is up for download on its Github "releases" page. It may not accurately capture what was V0.5 (such as some sprites from V0.7 and V0.8 to avoid having dummy sprites as much as possible), but I did to my best ability. Not all sounds were replaced, the only sounds included are what was included in the source code (except Keen's hit sound, which was from V0.6.4). Sounds that are muted don't have a sound file in the source code. I am confident I made a proper PWAD to replicate a possible V0.5 of Freedoom.
