1. RegionFOUR allows users to play games from other regions on their Nintendo 3DS systems. It requires a Cubic Ninja game cartridge or copy and an internet connection to work. 2. The exploit may cause the system to turn black or freeze, in which case the user should force a power off and clean the exploit from Cubic Ninja by holding specific buttons in its menu. 3. Not all games are compatible with RegionFOUR, like The Legend of Zelda: Majora's Mask. The user must relaunch RegionFOUR to switch between out-of-region games instead of directly pressing the game switch button.

1. Friendly Tips on Using RegionFOUR
Currently RegionFOUR is out by Smealum who is famous for Ninjhax and
regionthree. You can get all the files and instructions for RegionFOUR from mine
previous blog. Here I would like to share some tips by us(www.dwtechz.com) using it.
1. The correct working firmware is old 3ds/new 3ds /2ds latest 9.7 or 9.2, not from 9.2
to 9.7. The good news for regionFOUR is hacking new 3ds even the top version 9.7.
2. When you go to the load exploit after scan QR code, then it turns black or dead.
What will we do? Please force to power off and clean the save exploit installed on
copy of Cubic Ninja. Keep holding L + R + X + Y in Cubic Ninja's main menu. Try
again.
3. RegionFOUR needs Cubic Ninja game cartridge or a copy of the games (SKY3DS
is available) from your region and internet access. Each time you start regionFOUR
when you want to play out of region games on your console because unless you
save exploit to your Cubic Ninja but that is not recommended.
4. It is not every game working with RegionFOUR such as The Legend of Zelda -
Majora's Mask.
5. You can enjoy region free and homebrew at the same time only when your console
is right there, you know ninjhax runs on old 3ds firmware between 4.0.0-7 and 9.2.0-
20. and new 3ds needs 9.0, 9.1, 9.2, top version is just to 9.2.0
6. Tell a somewhat fool advice, how to quite the game? First time press home button
then pull off the card, secondly press home button again.
7. When using regionFOUR, you can't switch games by pressing blue button(sky3ds
card ) directly because you remember that console can't read the next out of region
game you want to continue to play, you should remember the order of games then
switch to the right game position and launch regionFOUR once again. It is better that
the steps is easy.
