unsorted.7z
unsorted.7z is the name of one of the leaked archives from the Zammis Clark Breach. It was leaked on May 2, 2020, on the 4chan board /ppg/. unsorted.7z was basically the first ever instance of a "gigaleak". It was the first of these leaks to gain widespread attention, including a video made about it by Modern Vintage Gamer, which gave it lots of attention, but also led to many misunderstandings, due to false claims made in the video.
Contents of the archive
The archive contained dumps of the "bb" and "ng" development trees from BroadOn's servers, likely sent from BroadOn to Nintendo. The "ng" tree, inside a TAR file named "depotrvl", contained a CVS repository with the source code for the Wii's input output system, source code for Wii factory software, the source code for boot0, boot1, and boot2, internal documents and PowerPoint presentations related to BroadOn and Nintendo and the development of the Wii, and much more.
sd_boot
These leaked files led to the discovery of a software tool used in the Wii Factory Process called sd_boot. This contained a vulnerability, which was found by Fullmetal5 and could be used to install BootMii as boot2 on Bollywood Wii consoles with a patched boot1.
