Kaze Emanuar on Youtube passes along the info that Rare’s terrific N64 platformer, Banjo-Kazooie, has been decompiled (7 minutes):
What does that mean? It’s that they’ve created source code (up on GitLab) that, when put through the same C compiler that originally generated Banjo-Kazooie’s object code, produces an exact binary image of the game. They can now rebuild Banjo-Kazooie. They don’t know the original variable names or any comments that were in the code, so it doesn’t mean that the code is perfectly understandable, but it is a major breakthrough in using the game engine for other things, including game improvements, mods, repurposings, and even compiling it for other platforms.
One result of this is that we now have a complete list of the codes that can be entered into the infamous Sandcastle Room, which are obfuscated in the original binary. The Sandcastle Room is a board of letters on the ground in the second level that can be used to spell things out, and if the proper text is entered it can unlock things in the game, or even enable the items in the abandoned “STOP N SWOP” feature that had been planned to allow players to transfer data between cartridges. If you decide to take a look yourself, the codes are listed out in the file named code_3E30.c.
