JiffyDOS protocol? #1

Thanks for making this handy script! Have you looked at decoding the JiffyDOS protocol at all? I'm not sure if the VICE logs are enough, but I've been looking at some specs here: https://github.com/MEGA65/open-roms/blob/master/doc/Protocol-JiffyDOS.md

I am testing some software and ran into a case where decoding the JiffyDOS would be handy too. I might look into it further but I didn't want to spend too much effort without check with you.

I haven't personally played with JiffyDOS, no. Michael Steil was supposed to write a blog post on that topic, but it is still "Coming Soon" as of today: https://www.pagetable.com/?p=1324

His video covers "Fast Loaders" to some degree, so that might still be useful for you. https://www.youtube.com/watch?v=_1jXExwse08

The other place I know to look would be in the sd2iec's emulation of the protocol: https://www.sd2iec.de/gitweb/?p=sd2iec.git;a=blob;f=src/iec.c

Good luck!
