Putting the flag to good use, I was able to restore the messages that were different in the original games themselves.
Aside from that, I also made some improvements, such as:
- Replacing the secret discovery message based on the GBA version with "You found a secret area!" akin to the 2019 re-release and Strife.
- Restoring voice lines when you quit the game in Strife.
- Replacing Doom's quit messages referring to DOS with ones from Doom 95.
- Adding a replacement obituary for the Schutzstaffel (or rather Schutzkämpfer) soldiers when playing on the Unity version of Doom 2, since Nazi-related content are censored in that version.
