This one sat in the inbox and marinated for a while, but thankfully the random page tool pulled through and reminded me that this exists. I used to joke that I'd give my left kidney for a prototype of Super Mario World; we came pretty close.
The gigaleak is so large that there are still teams of people crawling through it, organizing it, trying to recover and match different versions of assets and the like. There's so much that a lot of it is still waiting to be found, just from, well, how big it all was. When it first came out, there was a lot of initial hype around it that died down a bit later once all the "obvious" stuff was found, but there's still plenty getting added over time.
Link's Awakening, its source code, and various iterations of earlier assets definitely count, too. If only we had an actual prototype, alas...
