There are now a lot of different firmware is available for this device. The main ones are The default one which comes with it. And cross point. There’s another one called Sumi which is quite popular, but crosspoint is probably the main one, even More popular than the default probably.

Crosspoint ads quite a lot of functionality to the EPUB reading.

To be honest, I don’t really understand all the variations of E pub yet.
I sometimes find that the books I’m reading don’t have the chapters marked out properly. I’ve tried to use calibre and an extension of which I forget the name to fix this but it didn’t basically. So, I’ve tended to read books which are well mapped and good files instead!

There has been another problem with crosspoint and EPUB though, which is that there’s been a few times with these broken files only where I’ve turned on the device to find that the Book is at the stage I was reading the previous time I read it so it hadn’t updated my my progress, Because those chapters aren’t working is a real pain in the neck to get back using the percentage navigation instead of chapters. So far this has been the main problem I’ve had with the device. However, I’ll work again on this a bit more and see if I can fix this kind of problems. The great thing about the this device is that the code is so small and with vibe coding and all that you can potentially get in there and fix these kind of problems.

Personally, I want to add auto syncing so that a child’s device can be updated when it connects to a Wi-Fi point automatically and get the latest books from a server of some kind. Actually, Bluetooth might work better. Sumi does Bluetooth really well that way. No need for an access point you can use a Bluetooth enabled browser on iOS to transfer false cross for example.
