Minimal example: transcode from MP3 to WMA:

You can get the list of supported formats with:
ffmpeg -formats

picotron is in early alpha -- it doesn't seem to have a sprite editor yet but it does support sprites in a particular format, so I threw together this aseprite exporter.
picotron is out! importing sprites is still a bit tricky, so I built this script to help, along with this picotron cart
this script works great for pico8 too -- I use it often
you'll need Aseprite to use this.
