1. Extract savedata from cartridge.
2. Open & Edit savedata with an hexeditor.
3. Reinject the savedata.

You have to do your own research on the data's offset.

DO you think everybody you has made a save editor for the 3ds knew how 3ds saves work and how to change them the instant they gained interest?

an idea of how this kind of things work is all you need sooo... im not trying to offense you dude! if you ever make a save editor for any 3ds game ill be grateful to you and be happy to use it:]... im just saying if you know some kind of hex save edits just post that! and leave the save-editor creating to some1 else....

Aren't the save games encrypted? Don't they need to be decrypted first?

when you extract the saves (by using savedatafiler or any methods) usually they are decrypted already, unless another layer of encryption is present, like in MH4U saves

Thank you. So the save data that's stored in the NAND or on the SD card is encrypted? When using the Gateway to extract the save data from a retail cartridge, it's decrypted generally? Unless there's that other layer of encryption like in MH4U saves?
