The Simpsons: Virtual Bart was released for the Super NES and Mega Drive / Genesis in 1994 by Acclaim. KeijiDragon (Kei) has recored some videos from an interesting prototype of the game, that is somewhat different from the final version. You can check the annotations in the videos for more details:
Japanese Super Famicom (the Japanese Super Nintendo) pre-release prototype of The Simpsons: Virtual Bart game. Why is it Japanese? The ROM header states that it’s “run” on Japanese systems, or something like that. There are lots of differences in this prototype that are between large and small, and this video goes into detail what’s in the prototype.
Thanks a lot to KeijiDragon / Kei for the contribution!
