does this mean we can finally do something with those eggs, the key, and the door in the desert?
I must admit I also clicked the link expecting something to do with eggs and crystal keys.
I'm so glad somebody else remembers that.
It was years after the game came out, and was perhaps just a side-note in the videogames magazines, meaning that nobody believed my childhood self when I claimed to finally obtain the eggs.
FYI a spiritual successor to B-K appears to be in very early stages of development. https://twitter.com/MingyJongo
I still checked for years. In fact if anyone is interested in the full breakdown:
The technology that would have made this possible through what was known as Stop N' Swap. Turn off one of the games, then while the data was still in the RAM of the N64, place the other game in the console. However, Nintendo had made a change to the console that made the time the console clears the RAM post-shutdown to 1 second, making this method impossible. (Tooie had an alternate method to get the items in that game alone, where they did grant bonuses)
In Kazooie, however, in-game cheat codes were discovered that let the player get the items anyways, although they had no function.
