That's exactly what the person I quoted asked.
Now the wording is vague and could be interpreted either as:
a) Sharing the account credentials or b) Sharing AccountSwitcher profile backups
It makes no sense to ask a), that's always been possible. And b) can't be done.
That's pretty much it...
I think this goes without saying, but I'll say it anyway since not many people are mentioning it: This right here applies to every homebrew out there, mine included (AccountSwitcher). There's nothing stopping a dev from sending your credentials to a remote server. If possible, always compile...
Reporting my results:
Setup:
-O3DS 9.2 / Emunand on latest FW
-Acekard2 (2.1, not i) w/AKAIO
Rxtools 55d2622 and elf. Did not work.
CIA on EMUNAND NAND. Worked.
Gonna try rxtools e2c1e58 in a sec and report.
Anyway, one way or the other, this is fucking awesome. I was about to get an acekard...
I installed it to NAND instead of SD. :/
Once I removed them, I installed it to SD on my sysnand and it worked perfect. After that, I installed it on my emunand, and problem solved.
Again, I'm an idiot. Only DSIware goes to NAND, apparently.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
