chocolate doom default strings

[a2ko]

I can't find where the default strings are defined in chocolate doom's source code, all I can find is references to defined strings in a DEHACKED lump. I'm specifically looking for hard-coded default strings if any, else where does chocolate doom find the default strings to display in-game?

Edit:
I don't want to use DEHACK patches.

Vanilla DEHACKED strings: https://github.com/chocolate-doom/chocolate-doom/blob/master/src/doom/d_englsh.h
BEX strings: https://github.com/chocolate-doom/chocolate-doom/blob/master/src/doom/deh_bexstr.c

Oh, thanks. And I just realized that some strings (ex. menu options) are graphics within the IWAD that's why I can't see them anywhere.
