ROM Hack Super Mario 3D Land EUR SAVE Hack, import problem

[merlin555]

I have problem to import the gamesave from Super Mario 3D Land EUR Version.
Everytime when i imported the save, Super Mario 3D Land reports that the save is corrupt.

I doing following:

Export the "000400000FF40A00.sav" from the Titleid 0004000000053F00.sav moved.
With "Y"

I edit the file SD:\3DS\SAVES\Super Mario 3D Land\04\filer\UserSaveData\20150203112455\0000053f\GameData.bin with a HEX editor.

Offset 2B90 and 34D0.. very easy! (to 63) 99 Lives

Then the problem i see, its the importing.

Import "000400000FF40A00.sav" from the Titleid game save 0004000000053F00.sav moved.
With L+A.

Then i rename the file 000400000FF40A00.sav to 0004000000053F00.sav.

But the Super Mario 3D Land reports that the gamesave is corrupt.

The problem is the importimg is not correct.
What i doing wrong?

Maybe there's a checksum?

i have a normal HEX editor.

have no clue for checksum making.
