Questions ABOUT Gateway 3DS

Gateway 3ds is one of hot sale 3DS flash kit for 3DS 4.1~4.5 Nintendo 3DS. Gateway 3ds offers incredible features, Muti-rom, EmuNAND,100% game compatability being sure to excite 3ds fans. At the same time, would like to introduce some functions in detail to clear some guys confusion.

Q: Does all current game work? What exactly is EmuNAND? Is it possible to transfer eshop game from ym 3ds to this? The game that truly got my attention is Professor Layton vs Phoenix Wright Ace Attorney. I know it is euro version, would it work with my USA system? As a matter of fact, does gateway enable region free play yet?
A:
 The Gateway 3DS card, as of now can play all games bar one: Tomodachi Life
 It is region free, and allows the playing of any region game on any region console.
 You cannot transfer your own E-Shop title to your Gateway card.
 Basically, flash carts all rely on a profile exploit that was in system firmwares 4.1 through 4.5 This exploit allows the launching of code that is not Nintendo's. This exploit is the very foundation of 3DS flash carts. It was patched in firmwares past 4.5, meaning if your system's firmware were to go past 4.5, it would be impossible to access the flash cart at all. Therefore, you would not be able to access the eshop or anything that required a firmware greater than 4.5 because it would lose Gateway access.

Since you have to have 4.1 to 4.5 for Gateway in order to use it (with no exceptions), but would ALSO need a greater firmware in order to play newer games as well as access online features such as eShop, EmuNAND was created. EmuNAND is literally a copy of your system's firmware that runs from your SD card instead of your actual system's internal storage. The console can't tell any different, but it is actually from a different source entirely, and operates independently. If you download a game on your emuNAND, it is saved to the SD card copy and will not show up on your regular internal NAND copy of the 3DS. It is the same case with your internal firmware. If you downloaded or installed something on your regular internal NAND, it will not show up on emuNAND.

The emuNAND can only be accessed after having running unsigned code, so the emuNAND itself does not need to actually have the profile exploit anymore. Therefore, you can update this emuNAND to newer firmwares like 6.X and 7.X and take advantage of being on the newer firmware. The system's internal firmware just remains on 4.X in order to be a "gateway" (via the profile exploit) to launch a modified, newer, emuNAND where you will do all your future operations from.
