Many early video game projects and source codes have been lost to the sands of time. However, a recent leak may reveal information about many of Nintendo’s early projects. The Nintendo “Gigaleak” reportedly includes source code for games like Super Mario Kart and The Legend of Zelda: A Link to the Past. 

The leak recently appeared on 4chan in /v/, a video game forum. Some believe that this particular leak is related to another one that occurred in May. The servers of BroadOn, a company that was hired by Nintendo during the era of the Wii, were reportedly hacked.

Users are still digging through the leaked information, but an image of a list appeared on the 4chan. The list includes the following:
  • Full development repository for Ensata official DS emulator
  • Full development repository for Pokemon Diamond and Pearl
  • Full development repository for NetCard ([canceled] GBA peripheral)
  • Full development repository for Game Boy Advance BIOS
  • Full development repository for Game Boy Color Boot ROM
  • Full master ROM database for Famicom and NES including ROM
  • Full development repository Wii Shop Channel server-side source code?
  • Full personal development repository by a Diamond and Pearl dev
  • Master ROM of, (maybe source code') Super Maria RPG
  • "WallPaperPasswordMaker" source code
  • Random test program source code
  • Many tape backups
  • Several Super Mario World 2 prototypes

They have also supposedly found the source code for these games:
  • Star Fox
  • Star Fox 2
  • The Legend of Zelda: Link's Awakening DX
  • Wild Trax
  • Yoshi's Island
  • Mario Kart
  • F-Zero
  • The Legend of Zelda: A Link to the Past
  • Super Mario All-Stars
  • Wii [Virtual Console] Game Boy Emulator
It is important to note that the above list is not comprehensive. One Twitter user looked through the leaked data and found evidence of a Pokémon MMO. Players who played the game offline would have had access to thirty Pokémon, while online players would be able to catch a greater variety of Pokémon. The game was reportedly proposed in 2004 and players would have needed to connect their Game Boy Advance to a PC.

This is a fascinating look into Nintendo history if this leak is the real deal. For example, the NetCard is a canceled Game Boy Advance peripheral. There are also a few concepts that are included in the source code that never made it into the final games. Yoshi’s Island was once supposed to include a minigame where Yoshi stole items from Bandit and placed them into Baby Mario's cart. There are also various prototypes of Yoshi, Donkey Kong, and even a human character in Star Fox 2.

It is important to take all of these leaks with a grain of salt, especially given the source. There has been quite a bit in the news lately about vintage Nintendo products and more recent nostalgic collaborations. For example, a sealed copy of Super Mario Bros. sold for $114,000 at an auction. Nintendo has not confirmed or denied the leak and they are unlikely to provide any comment.
