Honestly, you could get alot of money from selling your sky3ds blue button, as they're always in demand. With the money you could make from that, you could buy a DS flashcart compatible with b9s, that would allow you to install a full cfw. This allows you to play all of your game backups without the need to worry about security, compatibility, or private headers, though you only need to buy the flashcart on 11.4 and above, which I assume you are on. If you do not want to this, fine by me, it's just a suggestion.
