Powersaves

[brunorafaelsouza1]

Hi. I'm new here and I hope someone can help me.

I have a powersave and some games i made backups on it. But I lost my games cartridges and im planning on buy new ones. My question is, will i be able to use the same backup files on powersaves onto this new games? 
I've also read in case doesnt work, i can restore using Pkhex and a homebrew on my 3ds.

Please, I hope someone help me.

if you don't have the original cart or the xorpad (using the cart at some period in time), you aren't getting the data back.
