no, so i get to the step where i can create or migrate an emuMMC:
I can't migrate because none of the options are available. When I try to use the creation tool (I select SD File) it thinks for a moment and then gives me 'Failed to init emmc!' error. I asked in the discord about this and some users are saying that creating an emuMMC is impossible if I can't boot my emmc so now I'm not sure how this was meant to work to begin with, I might be missing something.
yeah, me either unfortunately. I was excited about the possibility.
depending upon your skill/tools it looks like you’re back to buying one of the $25 emmc boards from eBay/aliexpress or doing a r/r/r like @Donnie-Burger mentioned.
