Currently on 4.2 emunand ect. Could I upgrade to 9.2 and downgrade the mset to 6. Retain all current features and be able to keep my saves on my current system without the corrupt message? Same features I mean pokemon inject exploit boot rxtools through profile emunand latest for eshop access. I don't play roms or anything like that. Just want to use my actual games but all the saves are current.
