Backing up a Pokemon Red save file with ACE and a Microphone

What is this?

For a complete explanation and guide, see the writeup

How do I use the code?

The sending folder contains the assembly code to read and send a save file over audio. If you have RGBDS installed you can compile it into a standalone ROM using make.

The receiving folder contains the Python script to decode an audio recording. If you have a wav file called recording.wav you can decode it using python decode_save_file.py recording.wav.
