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
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 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
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! #gigaleakpic.twitter.com/A4piL0n4ev
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.
