Is it still being maintained? There used to be a game jam, Octojam, that was stopped years ago[0]. Seems mostly out of a lack of interest? Would be cool if it revived.
It inspired me to start zig8[1], my own CHIP-8 emulator. It's not ready for prime time yet but it's getting there. When it's ready I hope it will have a visual debugger and feel good: fast, better shaders, better sound, good defaults, etc.
CHIP-8 is a neat system. If you're interested in emulation it's a great place to start in my humble opinion. It's simple enough that you can finish it before deciding whether you like writing emulators.
Hopefully interest in CHIP-8 would pick up again, it's a neat bit of history and a cool little system.
Yes. I consider Octo feature-complete, but I still address bug reports.
I'm running a jam that starts Sunday called Langjam Gamejam that might interest you then. You have to make your own language and then use that to make a game. We have >120 people signed up and I'm expecting quite a few of the submissions to be similar to Chip8 or PICO8.
