Advent of Code 2021 - On an NES
Quest to complete Advent of Code 2021 on a unmodified 8-bit NES.
Should (and does) run on physical hardware. Uses MMC1 with 0x2000 (+0x800) bytes of RAM. Some of the challenges take way over an hour to compute the answer for. Does not work with PowerPAK (dont know why and at this point, I dont care).
If you hate yourself and want to watch it for the serveral hours it takes to complete, just:
(cd nesasmsrc && gcc *.c -o ../nesasm-fix)to build the modified (required) nesasm version../build.sh- Run it and wait a brief eternity for it to finish. The awesome christmas tune was ripped from here. Music does not loop so the vast majority of execution is spent in silent anguish.
EDIT: I just added the ROM image... Just load it in your favorite emulator or write to cart.
Days completed: 1,2,3,4,5,6,7,8,9,10,11,12,13,14. All of them! :D
