Advent of Code 2020

I'm archiving and cataloguing /g/'s collective attempt at advent of code 2020.
Day 6: things are way too easy. /g/'s not happy, and the filter hungers. Don't worry, I'm sure there'll be a ferry that needs us to patch its ROM or something.
Day 8: the bytecode has finally begun. And we literally had to patch a gameboy's bootcode. Nice.
Day 9: No bytecode continuation, but at least we got another brute-force O(n^3)!
