Hello people, I deff am an uber n00b at this stuff. lets get right to it, I have 3 new 3ds's one is a newly updated (my bad) US NA modle, and the other 2 are JAP 8.1.0 firmware. okay what i would like to do is the make it so my Japanese DSs can play US games. or if that isnt possible for my US mahcine to play JAP Games. I just today got a copy of CUBIC ninja, but as I said earlier my US new 3ds is at the latest firmware...11.0.0-33U Can anyone help me. Thanks So much.
Well if your only intention is to play out of region games that you already own, homebrew access is the only thing you need. This is possible on all 3 of your consoles, though for the US one, you'll need something other than Cubic Ninja (FreakyForm Deluxe being the best choice right now).
As for your 2 Japanese 3Dss, all you need to follow is this:
1) Download the starter kit here:
http://smealum.github.io/ninjhax2/starter.zip
2) Place all the contents from the .zip file onto the root of your SD card and place it back into your 3DS
3) Turn on your 3DS and make sure your internet connection is working
4) Start CUBIC NINJA on your console, choose "Create", then "QR code", and finally "Scan QR code".
5) Scan the QR Code you made for your specific firmware version (generate here: under the Get Ninjhax bullet
http://smealum.github.io/ninjhax2/ ) . This step might take a couple tries; make sure you fill up as much of your 3DS's screen with the QR code. If scanning the QR code returns to menu with an error, try a few more times.
6) Follow the on screen instructions. You may choose not to install the exploit to your gamecard's savedata, though doing so is not recommended.
7) Once you're inside of Homebrew, open up the RegionFree App and run your US games

Thank you for replying!
Is it possible to run roms without buying a flash card? Some sort of softmod?
3DS and emulator roms are able to run without an additional flashcart once a CFW is installed. If you want to play DS games, you'll have to buy a DS flashcart or wait for the DS emulator to progress enough for the games to be playable (
