ROM Hack Anyone knows how to back up eshop game?

[Wekker]

I know that the save file of a .3ds type 1 game on gateway is stored in the SD card. Those save can be copied to somewhere else for backup.
How does it work on a e-shop game like pokemon picross (downloaded from e-shop, not on gateway)?

A backup of the save you mean ?
Well if you use a Gateway (which means you have sigpatches), you can use Save Data Filer. There is a tutorial that even explains how to modify it for Pokemon Picross here.

Select the game on the home menu. (Click on it without opening it.) On the very bottom of the screen there should be an arrow if the game can be backed up. Just click on the arrow and then save-data backup. Or you could use SVDT if it isn't supported.
