You’re quite right - my apologies, I had thought that I’d managed to do what I described above with the PP starting on a red LED as well as enabling me to access USB mode with the blue LED Up volume button (i.e. indicating that Tow-Boot was still the functioning bootloader) but I just tried to replicate that and my PP started with a green LED then displayed Megi’s multiboot menu so I can only assume I got slightly muddled when I first tried this late into the night...

Ok so there’s no way of having ones main OS on the microSD card, Megi’s multiboot on the eMMC and be able to switch between the two without removing the microSD card?

I think you could do that in two ways, both using p-boot. One is to remove the bootloader from the uSD so that the process skips the uSD and uses the p-boot on the eMMC. The other is to install p-boot on the uSD. In either case you'll need to check the p-boot docs to see what config changes you need to make to p-boot to provide the extra boot options.

Hmm that’s effectively what I thought I’d achieved by putting a more recent build of Mobian on the microSD because IIUC Mobian’s removed the bootloader from their recent builds since they’re now relying on Tow-Boot being in place...but yeah as we’ve already discussed, Megi’s multiboot currently only works with p-boot and Tow-Boot doesn’t recognise p-boot as something into which to boot.
I’ll see what I can manage with getting p-boot on the microSD!
