I love how the post, about N64 graphic tricks, ends with the question: "Is this the future?"
The system has seen a dozen of its most popular games decompiled [1] into readable source files, which enables easy porting to PC without an emulator. It also enables a ton of mods to be written, many of which will run on the original hardware.
There are numerous Zelda fan remakes [2]. Complete games with new dungeons and storylines.
The Mario 64 scene is on fire. Kaze has deeply optimized the game [3], and is building his own engine and sequels. If you like technical deep dives into retro tech, his channel is literally golden.
Folks are making crazy demos for the platform, such as Portal [4], which unfortunately brought Valve's lawyers' attention.
Lost games, such as Rare's Dinosaur Planet [5], have leaked, been brought up to near production ready status, been decompiled, and have seen their own indie resurgence.

Curious - why the desire to have it run on GL 2.1?
Turns out that perfect precision weapons on a m+kb setup are actually not much fun to play with. The movement is so limited compared to the brutal precision a mouse offers that everything just dies really really fast.
