You don't use the 8.1 to log in. What you do is leave your SysNAND at 8.1, and create EmuNAND, then update the EmuNAND to 9.5 and log in from that. Nowhere in the process do you need 9.2.
If you are adamant on getting on 9.0-9.2, then the only game cart that has that update is a newer batch of Super Smash Bros. It comes with 9.2.0.20 iirc, but you cannot tell the difference via box from the 9.2 cart or 7/8.x cart (not sure if its 7.1 or 8.1)
Crappy Tiny Reader 1.8 (by Psycho) will fit the bill. It's getting harder to find these days so I've uploaded and attached it.I have dumped my retail Smash cart. Is there a way for me to open the ROM and see the update version?
YesIt's possible to update emunand with a rom ?
For exemple. I'm on GW3D Emunand 5.0. I want upgrade my emunand to 8.2. It's possible to use a rom with an 8.2 update ?
To log in to nnid you need to do so on both sys and emu nands, if you only do it on emu it gives you and error every time you try to access eshop. I can't log in while on 8.1 since it says I need to update to do so.

There are some that may have specific reason to be on 9.2. Compatibility with certain retail game saves while in classic mode being a big one.
Also those who want to use most spiderhax homebrew.

Yes
Hold UP when you boot GW mode, it will disable firmware spoofing and let you update emuNAND with a ROM.
But why? emuNAND works fine with 9.5.
That's another matter, I'm not sure if that's possible.Because i want to update my sysnand with a rom without emunand on sd
