it's spb/obf only!!! so no pagesets. but I did open an issue on github with sps->obz conversion suggestion. So we'll see what happens with that.
(if anybody reading this happens to know about coding & wants to maybe contribute, an sps file appears to be some sort of sql... i don't know what to do with that, though.)
it IS an offline .html converter, also! So it brings up this nice webpage to convert things for you:
(the conversion was an attempt at file renaming the lamp hack .sps to .spb. it did not actually work.)
interestingly, a page bundle seems to *also* download as spb... but when i converted the aac core compared page to check, it's only the p2g page? Not really sure about that, either.
so if you have a single-page board you want to convert, it'll work fine, but entire pagesets... not so much. (Yet? Hopefully. haha).
I assume offline html is possible on a phone *some*how, but I've never really looked into it, so... probably best to have a computer?
