It’s becoming increasingly apparent that, on the subject of Nintendo source code leaks, there is a lot of tangled information. It was believed back in May that a massive leak of Nintendo console source code had occurred, but it apparently was an exaggeration based on incomplete and confused information. Today’s new alleged source code leaks come via Resetera, sharing an anonymous posting on 4chan. That means — proceed with skepticism. Nonetheless, there are claims that full development repositories have leaked for Pokémon Diamond and Pearl, the Game Boy Advance BIOS, and the Game Boy Color Boot ROM. Additionally, a full master ROM database for Famicom and NES has allegedly been located. Source code for numerous SNES games like Super Mario RPG, Star Fox and Star Fox 2, a Super Mario Kart prototype, Yoshi’s Island, and more are apparently available as well.
Prototype SNES videos leak as part of the alleged Nintendo source code leak
The most compelling evidence that these Nintendo source code leaks really occurred is the fact that some wild videos have already begun circulating online. For instance, there’s this alleged Super Mario World prototype, with a big-nosed weirdo of a protagonist running around. (The music in the video is not part of the game.)
Then there are these curious videos for a Yoshi’s Island prototype and an incomplete version of Super Mario Kart (plus music).
There's also this slightly broken Super Mario Kart build with no drifting (?) and unused tracks, including a unique title theme
Versions of games like Mario All-Stars and Mario RPG have also been found and are being researched into rn pic.twitter.com/YMHaiLjXmd

Also, Bowser with legs in Super Mario World and a human in Star Fox 2?
People are digging up all sorts of unused art assets from the latest Nintendo leak. Here's some screenshots of some examples. Bowser from SMW apparently had legs at one time? pic.twitter.com/EZGDjiGAx6
