Repository doesn't contain input files, input data is read from input/day??/input.txt locations.

The recommended way of building for 8-bit targets is opening this project in VSCode devcontainer (required configuration is included). To run day01 on llvm-mos 6502 simulator, execute following in VSCode terminal (inside of dev container):

cargo run -p day01 --release

To build executable for atari800 do:

cargo build -p day01 --target mos-atari8-none --release

Atari executable file will land is target/mos-atari8-none/release/day01

Project contains Makefile which may be used to build all solutions for Atari800 with single make command (all input files are required in input/day?? directories). For each day atari .xex and .atr files are created in target/mos-atari8-none/release/ directory.

Native executable may be built without devcontainer, but nightly Rust is required:

cargo +nightly run -p day01 --target x86_64-unknown-linux-gnu
