Hackers have now found a way to disable the region lock on Nintendo 3DS consoles. The method allows you to play legitimately purchased overseas titles on your Nintendo 3DS. To enable this feature you must be running v4.5 firmware or older, if you aren’t then this specific hack won’t work. You will need to use a Nintendo DS or Nintendo 3DS flashcard which works with legacy firmware. This will enable you to run a patched launcher file that modifies your system to load cartridges from other regions. You can also update with more recent firmware afterward to play imported games that require it.
