Hello,
sorry it's my first venturing here since been offered a Switch that happens to be in v3.0 and hackable, so I'll ask lots of questions!
1/ Can I upgrade directly from 3 to 7 the OS?
a/Using "choixdujournx" I can basically do that without burning any fuse, meaning that I can rollback (up to v3) if I want later, right?
b/Is any version able to launch homebrews? Or is it locked to specific versions only?
2/ If I understand well, emunand is copying the OS to an sdcard (or elsewhere) in order to launch the copy ?
a/Can I play online games on emunand? If so, is there a ban risk?
b/Are emunand tweaks and parameters saved or is it read only?
c/Can I have an emunand version different from the system? (ex : sys at 3.0 and emunand at 6.2)
d/What is recommended, using emunand as a separate partition in sdcard, or a file in the sdcard?
3/ I don't want to use the jig every time to boot on CFW (SXOS probably), so I want to use the auto-crm feature : is that a known modification that makes the switch banned online or is it safe to keep it?
4/ What are the recommended precaution before doing anything? Saving/backuping stuff from untouched switch?
5/Is it still recommended to only use FAT32 sdcard instead of exFAT?
a/Is there any possibility of supporting ntfs or ext2 in the future by CFW?
