Doomsday Engine

Is this related to the "standard" (cough) that Doombuilder mentions? The folder structure standard?

perhaps an alias that Doomsday falls back on.
e.g.: other ports put graphics in

/textures

and sounds in

/sounds

While Doomsday uses:
/data/{game}/textures and /data/{game}/sfx

While no guarantee other ports' PWADS will run in Doomsday, this might help Doomsday PWADS running in other ports, all things being equal.

No, this is about using e.g., PNG textures in place of DOOM patch-format lumps.

...perhaps an alias that Doomsday falls back on.

Doomsday already uses the /textures and /sounds directories in PK3s for high quality replacements whereas "other" ports have since opted to use the same locations for new resources. I would need to look into whether both can coexist in the same location but I doubt it.

I was never able to put custom or replacement sounds in:

/data/jheretic/sounds/

only

/data/jheretic/sfx/

? So...
