A new project from Nintendo 3DS homebrewers, RegionThree, allows players to load games from any region on the handheld.
Compared to the universal Nintendo DS, the 3DS has been plagued by the inability to play games irrespective of the region they were bought from. Those in PAL regions are unable to play NTSC games, and vice-versa.
All that's needed for players to access this ability is to pop a file onto an SD card, run Download Play and access an exploit page on the Web Browser. Internet access is required to run the RegionThree exploit each time, however.
The file does not allow players to run homebrew applications or illegally downloaded content, just physical titles from other regions. Firmware versions 9-0 to 9.4 are supported, but New Nintendo 3DS consoles aren't. Creator smealum isn't planning on supporting the newer hardware models, but the code is available for someone else to give it a crack.
For details on RegionThree and to download, be sure to visit the project page on GitHub.
