This guide has been rewritten due to Sharkive no longer being a valid method, as Sharkive's functions are now available in Checkpoint (version 3.7.0 and onwards).

Make sure Checkpoint is up to date! (Version Number in Top left corner)

1. Open Checkpoint
2. Select game from list
3. Tap "Cheats" button on lower screen.
4. Using Up/Down dpad buttons to move through the list, and A to select, select the cheats you want to have.
5. Press B when done, then A to save the file.
6. The cheats for your game should now be in Rosalina's cheat list (button combo for Rosalina>cheats)

This guide is up to date as of 02-18-2020, 16:18 (4:18 PM in 12-hour)

If you're using Sharkive, don't use it. Use Checkpoint.

If you're using Sharkive, don't use it. Use Checkpoint.

I found that out when i read later post

When I open Sharkive, it says "loading, please wait" for about 5 seconds, and then it closes itself. I have tried both the .cia file and the 3dsx file and gotten the same results. Is there any way this can be fixed?
EDIT: I was looking through this thread and realized that checkpoint already has cheats integrated in it.

Yeah, that happens sometimes. To my knowledge, there's no real fix for it, you just have to deal with it.

Is there any cheats for the 3ds game Tomodachi Life. I want to get infinite in-game money, but I do not see any codes in Checkpoint. Is there a way I can download active cheats onto my CFW 3ds, so that I can cheat on my Tomodachi Life. I have tried a certain Gameshark cheat code on Rosalina, but it will not activate.

 

[REUPDATING]
