DOOM has been ported to the retro game console in Persona 5 Royal
DOOM is well-known for being ported to basically every device with some kind of input, and that list now includes the old retro game console in Persona 5 Royal. Modders KingJackSkellington and Xan1242 released the DOOMsona mod today, that lets you buy the shareware version of the original DOOM at the second-hand store in Yongen-Jaya. DOOM is fully playable and, like the other games Joker can play in his room, will grant the player a social stat upgrade when they're finished (in this case, his guts will increase) and prompt commentary from Morgana before and after playing.
The mod includes the WAD file for the shareware version of Doom, as well as for FreeDOOM and Chex® Quest, a promotional video game released by General Mills in the '90s based on Ultimate Doom. Upon completing the shareware DOOM, which only comes with the first episode, the player can purchase a full copy of Ultimate DOOM from the same store; however, since this game is still being sold commercially, the WAD file isn't included with the mod and the player must provide their own.
DOOMsona also supports any PWAD that is compatible with Chocolate DOOM, a source port of the original DOOM that aims for historical accuracy and adherence to the experience of playing DOOM as it originally released.
