Gaming Help! SD corrupted and can't play old saved games that aren't the latest!!!

[Xabring]

I hope this isn't the wrong place to ask, but, is there is a way to fool the 3DS into reading an old saved game? because I had trouble with an SD card that got busted, and couldn't rescue the data from it. And well, I got a backup of my 3DS folder and used a o̶l̶d̶ ̶b̶u̶t̶ ̶w̶o̶r̶k̶i̶n̶g̶ new SD, but of course, the games that I played often are the ones affected, those a̶b̶a̶n̶d̶o̶n̶e̶d̶ games that I didn't play before the backup where unaffected, but the saves that I lost that hurt me the most are the animal crossing and the smash save data. I can eat the smash data loss, but I don't take the one about the animal one since it's basically the one I w̶a̶s̶t̶e̶d̶ invested more time in it and well, got some nifty stuff there.

in resume:
is there a way to fool the 3DS into thinking the save is the most recent save?

thanks beforehand
