how to backup with powersave and use the file on gateway ?

[aos10]

i tried to back up pokemon ruby ( my own cartridge ) , it save it as .3DS file

but when i try to launch the game it says the save is corrupted

i tried using program called cart2sav , it produced a 1 mb file , pkhex didn't accpet it

is there a way just to decrypt the powersave save game and use it on gateway ?

That's always going to happen because GW so far doesn't support card2 game backup/restoring. You have to start that rom game over, save the game (doesn't matter when and where), go to SDF to export save, then restore a decrypted powersave (renamed to "main") to the appropriate folder generated by SaveDataFiler. The folder is named by date and time of exporting, 20150129074313 for example, and the subfolder's name is the ID number of your cart (my OR has an ID number ending in 11c4). There's a website that tells you 3DS id numbers, in case you backup more than 1 game and get lost.
