To compile, make sure you have devkitarm and libnds installed, then run ./compile.sh.

Input files can either be compiled into the binary or stored in a folder called inp next to the binary (this does not work in emulators). If a folder called inp exists at compile time, the inputs from this folder will be compiled into the binary. The input files should be named {day}.txt. download_inputs.py will download your inputs and place them in the inp folder.
