A newly found cheat code for Sega Saturn's Doom enhances gameplay, discovered 27 years post-release. Explore the retro gaming news now.
A new cheat code for the Sega Saturn version of Doom has been discovered, 27 years after the game’s original release in 1997. This newly found cheat allows players to make walls in the game semi-transparent, offering a unique gameplay feature that was previously unknown.
I would argue that is less transparency and more overlaying the skybox texture. In the city map with the Pinky you can't actually see anything behind that wall, you just see the skybox.
Could just be "bad" examples but this makes sense. My understanding is that PC DOOM tended to use additive geometry in these cases so that the skybox is literally just a bigass box around the map. Whereas I assume the Saturn version had to do some magic to fit everything and may have used a different technique. Hence the ability to just overlay that texture over everything.
IIRC Doom didn't have a skybox per se, just parallax ceiling textures. You could put that texture on floors or ceilings and it would show the sky texture that would not be attached to the walls.
