I'm tinkering with a PlayStation homebrew (voxel space renderer) and development for fifth generation consoles has never been easier.
Modern toolchains, programming languages, dev cartridges and libraries from the community makes all the difference. Outside of some niceties like ICE (gotta write that GDB stub for target hardware at some point), it's not that different from what you'd experience with modern embedded work.
I am in the process of using Claude Opus 5 to build an N64 game, and it really works. I've written no code and it is able to build a fully functional game.
I got it to write a skill for driving the Ares emulator via GDB Remote Serial Protocol and it uses that for its feedback loop.
Super interesting article - thanks for sharing your journey. As AI slop takes over the internet, well written and original technical content like these will be important.
