Nice - thanks for the graph! Looks like you're dumping scanlines in an array? Using Uint8Array or some other typed array may be a lot faster and more memory efficient.
I'll look into the pretokenise - pretty sure it's an IDE issue with it using the wrong IDs for tokens, so I should be able to clear that up without a firmware update
