== IDMUS## cheat doesn't work with shareware/registered Doom IWADs ==
The IDMUS cheat allows the in-game music to be changed. However, in
the original v1.9 this cheat didn't work properly when playing with
the Doom 1 (shareware and registered) IWADs. This bug was fixed in
the Ultimate Doom and Final Doom executables.
Chocolate Doom emulates this bug. When playing with the shareware or
registered Doom IWADs, the IDMUS cheat therefore does not work
properly. If you are playing with the Ultimate Doom IWAD, the
Ultimate Doom executable is emulated by default, so the cheat works
properly.
