thats gmfreedoom right there

how did you get it to work with freedoom? When I try that the game just crashes

@Mr. Skops How did you got that working?? 😲

if you are using freedoom1.wad rename it to DOOM.WAD if your are using freedoom2.wad rename it to DOOM2.WAD if that doesn't work then idk what to do

Om..

I tried renaming freedoom2.wad to doom2.wad and that crashes the game when loading a map.

Ok so, the freedoom2 wad has a few placeholder files for some sounds (DSPEDTH, DSBSPWLK, DSFLAME and DSFLAMST) which were causing the crashes, I replaced them with silence and it worked without problems. Also the sound of the rocket launcher (DSRLAUNC) didn't play because gmod doesn't support the samplerate it was on, so I changed it from 16000hz to 22050hz and it worked.

@Elvis Cochuelo Sounds? What are you talking about? Gmod is unable to play sounds from wad files, it's a Source engine limitation.

@Zsombor99 gmDoom opens the wad file to obtain the sprites, sounds, textures, etc. and converts them into graphics and sounds that gmod can render.
