And a series of new videos and images of purported prototype versions of Yoshi’s Island, Super Mario Kart, Star Fox 2 and other games based on the leaked code have been released. It was also claimed to include the Wii Shopping Channel, a Game Boy emulator for the Wii, data from the iQue Player (Nintendo's game console released in China in 2003, based on the Nintendo 64), and a Nintendo 64 demo ROM (see video below).
The likelihood that this Gigaleak (as it's commonly known) is real is supported by Dylan Cuthbert, one of the major Star Fox developers of all time, commenting that he hasn't seen the tools he created for Star Fox 2 in almost 30 years.
Wtf - I haven’t seen this tool I made for StarFox 2 for almost 30 years, I wrote it in early c++ to teach myself the language more than anything else. Where the hell have hackers got all this obscure data from????!! https://t.co/9kN9UoQPMS— Dylan🗑️🗑️🗑️Scrappers is OUT! (@dylancuthbert) July 24, 2020
One of the prototype videos released is called Yoshi’s Island. In the title screen, it's called Super Mario Bros. 5 (the product version is Super Mario World 2: Yoshi's Island), the music is Super Mario World, and the user interface is different from the product version.
A bunch of Nintendo prototypes are apparently currently being compiled from leaked source code right now as of this post— Akfamilyhome @ Origami King (@Akfamilyhome) July 24, 2020
First up there's this Yoshi's Island proto with different UI graphics, placeholder music from Mario World, and has a prefix of 'Super Mario Bros. 5' pic.twitter.com/Qqock5RZaS
There was also a mini-game in which Yoshi transformed into a helicopter and collected eggs from an enemy vehicle and dropped them onto Baby Mario's cart.

Yoshi flies to steal various items from Bandit on its minecart, depositing them in Baby Mario's cart following behind. Bandit has a predetermined score & must be beaten by the time they hit the end of the track.#yibeta #yoshisisland #gamedev pic.twitter.com/TTUi0mG1YK
They've also released a Zelda 3-named Link and a prototype Yoshi graphic pattern that's filled with insects.

While international gaming media VGC has also released some prototype images, perhaps the most interesting one is that there is a human character in the animal game Star Fox 2.
Super Donkey, which seems to be a pre-alpha version (?) of Yoshi’s Island, also includes images and a video starring Stanley, who was active in Donkey Kong 3 with bug spray in hand. The tragic character, who played the lead role in the official numbering but never appeared in the later series, feels a little rewarded.
And it's not just Nintendo, there's also a prototype of Konami's Super Famicom version of Castlevania. The music seems to be slightly different from the production version.
Yo why is nobody talking about the prototype roms present in the leak? There is a Super Castlevania IV beta with no intro, missing graphics and unfinished music! There are also beta versions of Super Aleste, Ghouls and Ghosts and Axelay! #gigaleak pic.twitter.com/A4piL0n4ev— NyxTheShield (@NyxTheShield) July 24, 2020
If the source code and materials from which these videos and images were derived are authentic, it would be a serious violation of intellectual property rights. We hope that the person who hacked the server and leaked them will be identified.
