If you use emuNAND with 9.4 version, you can use saves.
Has anyone tried using a cartridge update to 4.5 after the 4.2 downgrade?
Do you have the Gateway?
Should work. Fast & Furious for 3DS has 4.5 update and is $15 on eBay.
Sorry for your sister.Didn't work. I downgraded her to 4.2 and loaded 9.4 emunand. Getting savedata corrupted on Pokemon Sapphire
No reason that shouldn't work.
so no one has tried to use CFW yet
Downgrade removes nag screen?
Luigis mansion as well but it cost a bit more
So far no which is mind boggling to me
