All sorts of N64 games are being decompiled ever since the compiler for SM64 was made usable on a modern system 2 years ago! Off the top of my head there's:

-The Zelda titles (led by Ocarina of Time at 64% completion)

-The HAL titles (led by Kirby 64 at 5% completion)

-Conker's Bad Fur Day (and other Rare games)

-Dinosaur Planet, which quite literally came out yesterday (which goes to show how easy it is to get an N64 decomp going, as long as the game doesn't use GCC)
