To date, we have seen many different mods for Doom, and we have seen that it works on different devices. The legendary game was even run on a smartwatch before. However, we think that this is the last point now. Because now they managed to play Doom in Doom.
A YouTuber named kgsws, who also hacked Game Boy Pocket before and is famous for creating a multi-screen Game Boy Pocket, took Doom this time. With a screen he designed in Doom, the kgsws that made Doom playable here, thus made it possible to play Doom in Doom. Of course, it goes without saying that this is a bit of a fanboy thing.
