Hacking CFW vs Gateway?

[astronautlevel]

Nope. I never read anything like that (except "formatting is advised (not even compulsory) before downgrading" but no one cares since you're already on 9.2). Or maybe a CFW so old I never heard of it.
And actually, if you're already using an emuNAND with Gateway on a 9.2 sysNAND, all you have to do is add some files to your SD and you can boot to your emuNAND (same one as that used by Gateway) from your CFW. And without having any red cart insterted as I said.

You almost definitely want to format SysNAND to unlink your NANDs.

You almost definitely want to format SysNAND to unlink your NANDs.

That of course. But the way he worded it made it sound like "formatting everything before setting up a CFW", while unlinking NANDs is formatting once the emuNAND is working and has everything sysNAND had (so nothing is lost when formatting sysNAND). Moreover, if he already has Gateway running, either he already unlinked and doesn't need to unlink again, or he didn't unlink for a reason and that reason still applies for a CFW (even though I don't see any reason).

I'm happy with my current combo of CFW + Sky3DS+. I haven't had the need to use my Gateway card until now.
