I have retail saves of (for example) Ocarina of Time that I played on a 6.0+ firmware. Recently, thanks to the Ultra Gateway firmware, I have been able to downgrade to 4.4 and use the gateway to play backup version of my games. But now, my 3DS cant recognize my retail cart save. And I do realize that's how it works, since the saving system changed after 6.0 or something. So, long story short, are either of these possible: 6.x+ retail cart save --> retail carrt on 4.4 fw 6.x+ retail cart save --> gateway backup rom on 4.4 fw Does what I am asking make sense?
