Hey thanks for taking the time to leave a comment!
The Playdate SDK unfortunately doesn’t support raw PDF or PNG images (at least with the Lua SDK), so I’m unable to add support for those. I do have it on my todo list to create some sort of app to do the processing automatically, but that’s not something coming soon.
A video tutorial is unlikely (from me anyway) as I’m not someone who likes to be on camera.
However! I can expand the instructions a bit. Where in particular are you having trouble?
