The tool I wrote in order to make "Bad Apple but its VIDEO is ported to Famitracker."
This is in no way a general tool; it is a quick and dirty script. You are free to try to use it, but it is very unlikely to work for your use case without changes. MANY assumptions about my extremely specific use case (song tempo, expansion audio, video resolution, file formats, etc.) are baked in. The output file is track data only, so famitracker module header data must be added manually, and the last segment's length must be adjusted too. It was easier to do this manually than to code my script to do it. Sorry!
