Hi there!
Since Pokémon games are excluded from the official cloud save backups, I'm trying to figure out the safest possible way to back them up locally, and whether it's worth the risk.
If anyone can answer any of these questions, I'd really appreciate it!
As far as I can tell, it looks like the safest way is by doing a full NAND backup with Hekate and also dumping my BIS keys, then extracting the saves on my computer with HacDiskMount.
1) Would that work? Would I be able to restore the saves to another homebrew-capable Switch if needed? (I realise I'd probably need to keep that one offline.)
2) Regarding the error reports that can alert Nintendo that you're running homebrew - are they only generated when running homebrew within Horizon, or could an error during a NAND backup in Hekate (or when using biskeydump) be reported the next time I turn my Switch on normally?
3) Apparently there's a "booted-via-RCM" value in the PMC registers. Does anyone know how that works? I mean, is it a counter that increases each time you boot into RCM, and could therefore look suspicious if Nintendo ever start checking it? Is it just a True/False that gets rewritten every time you boot? (Basically, if I never boot into Horizon via RCM, will my RCM -> Hekate boots be undetectable?)
