How I failed to make a game: Raycasting on the GBA

Shockingly enough it is actually possible to do decent ray casting and much more on the GBA despite the incredibly minimal compute budget.

Joshua Barretto has been working on a GBA port of Super Mario 64 with entire 3D levels, characters, and movements. In my opinion just incredible work:

The one that blew my mind as a kid was Need for speed underground:

I distinctly remember Spider-Man 2 on GBA having a 3D overworld. It was my first introduction to the concept of "low framerate" in a videogame haha. Incredible what people were capable of doing with the hardware back then.

There was actually a fully 3d platformer released for the system during it's production run, Asterix & Obelix XXL: https://www.youtube.com/watch?v=b0pknb4ghUA

I'm more impressed with the song "Get Low" ending up in an E-rated game.
