Hacking Question about saves on Gateway3ds

[jimskeet2002]

Hi guys
I have an old3ds and a new 3dsxl.
I have downgraded my old3ds to 4.5 and I have been playing with gateway on it.
My new3dsxl is on 9.0 and today I got cubic ninja so I will set it up for use with my gateway.

I have 2 questions

1) I have been playing luigis mansion 2 as a retail cart on new3dsxl. I have backed up its save using my old3ds from the gateway menu. Will I be able to use this save on my new 3dsxl with gateway? On my old3ds it shows as corrupt but I guess this is cause my sysnand on old3ds is 4.5

2) Since my sysnand is 4.5 on my old3ds will I be able to use the saves I have from it to my new3dsxl with gateway?

Ok the second question is answered I guess because I can load my saves from my old 3ds.

But when I cannot use the save from my retail card. Does anyone know how to transfer it? The game is luigis mansion 2 and it was played on New3dsxl 9.0. When I use gateway on my n3dsxl I get save is corrupt message
