And finally...

Which leads to...

It takes forever to load the program though, I'm going to have to see if I can get it to detect DMA. And there's not much to show once the program does load.

Impressive work, Arbee. If you can eventually distill it into a WIP page update rather than something I have to reconstruct from screenshots , I'll share it.

Not a bad idea. I'll see if I can write something up.

How can the emulated system know about the "MAME Compressed Hard Disk" Drive type? Is the drive type string read out of the disk or something?

yeah, unfortunately all MAME HDDs identify as that at the moment as the responses to the drive identify commands are simulated. At some stage MAME needs to start emulating the real drives, with the real drive timings, proper firmwares for the drive type at least loaded (even if the HLE identification remains) and proper capacities, CHS etc. for each drive (there are quite a few older CHDs in MAME with complete nonsense values in these fields at the moment)

it's just a bit of a hangover from when the CHD system was first introduced as just a way of storing large amounts of data, without caring about the actual drive types.

Zoofari made the VP101 board cheaper by replacing the high-performance VR5500 with a slower TX4925 SoC and then they reprogrammed the FPGA so nearly everything else was done differently. But once we found out what they'd done it wasn't so bad.

No, I don't know why it says the partition info is bad, it seems to go ahead and load the program fine anyway.
