What's SMF all about?

dressupgeekout commented 4 years ago

Forcing FFmpeg to process SMF files as if they were 22.05 kHz unsigned 8-bit PCM samples (mono) reveals that there is some raw audio data in here interspersed with some other data (image data?)

Been making some progress here. This is definitely "the" animation/slideshow format. Audio data and non-audio data (probably graphics mixed in with some timing metadata) are interspersed. There's a header which has proven difficult to interpret, but at least it corresponds to the length/complexity of the animation in question.
