Playing The Simpsons Doom.
Simpsons Mod Site: http://waltersgameboy.tripod.com/simp...
Put doom2.wad and the simpsons wad into the ZDoom folder. Then, drag the simpsons wad onto ZDoom to open the game.
Remember a different Simpsons Doom?
Yeah, there was a different one that was made earlier, but it's quality was a lot less than this one.
The song is "Lum no Love Song" from Urusei Yatsura.
About the music:
Yes, I know it's not Simpsons music. I'm assuming the creator of the WAD noticed the lack of music for the show, so they put in some recognizable songs. They fit in quite nicely.
About the switch sound:
If you think you know what it is, then you are right.
