Hello,
I red a lot of things about 3DS linker especially the Gateway which seems to have basic internal functioning. Indeed, they based the whole think on exploits to circumvent Nintendo's protection and authorize access of their linker into the system. The 4.5 firmware version exploit (and now 9.2 ninjax exploit but without emunand) allowed people to understand and reverse engineer the security protections of all firmware (using emunand to allow access to subsequent protection systems : ie new keys or additional security checks).
But how the Sky3DS works make me more sceptical...
As far as I can understand, the linker needs some sort of blueprints for every game (ie encryption or decryption key ? contained in the template file) so that the 3DS system can authenticate the cartridge of a specific game. I think the binaries of the games are stored encrypted into the Nintendo original cartridges; the 3DS system contains the list of all decryption key so that all games can be launched.
What is totally pointless for gateway linker (since all security are bypassed by the exploit), is mandatory without a kernel exploit. Thus, Sky3DS truly emulates a genuine cartridge and passes all security checks (even on the last piracy revised firmware 9.4).
So let's come to the sceptical part...
Since gateway team is supposed to be the leaders in the 3DS scene (they brought a lot of features and innovation since few months), why can't they do the same think as Sky 3DS ? They have also all access to firmware internal files, and should be able to found these de/encryption keys for each game and update the gateway to operate the same way as the sky3DS.
And last but not least, if the sky3DS is able to emulate a cartridge and since there will always be internal access to subsequent firmware version, How Nintendo will be able to block it ? since you will have the ability to modify the behaviour of the linker accordingly... In the best case (or worse depending on the point of view), they will only be able to implement new security patterns in future games cartridge (but again emunand access is not so far for indiscretion).
If someone has a different theory or fact please share...
