The writer for sky3ds won't accept roms that aren't listed in the linked template file, although I suppose you can build a .3ds that reads like an existing game to get sky to accept it... Not sure if that would accomplish much of anything

You would achieve nothing, the Sky3ds basically emulates a cartridge, takes the encrypted rom and transfer the information to the 3DS as a normal game would, all the checks are done by the 3DS itself, if you write unsigned .3ds files in a Sky3ds the 3DS would still refuse to read them.

? what? please explain me...
Which part? The digital signatures?

If we could sign our own software then it would appear as legitimate to the 3DS from the get-go and why would anyone buy a Sky3DS or Gateway when all they have to do is patch a few files and stick them on an SD card?

As far as I know, 3Ds software is encrypted with a special key known only by Nintendo, and every 3DS has the key to unlock said software and then it's own encryption for downloadable content. Which is why you can't just copy a friend's SD card and use their games on your unit.

wait that mean that 3ds files are un-encripted and the sky does the work of convincig the console that the file is a real cart? genious! didnt thought that sky does that... also that means that sky team cracked the autorization algoritm?

BTW there is no point in ANY flash cart when ya have a CFW-able console, in which case you just install CIAs.

No, they are encrypted. The template makes it look (to the 3DS) like they are being read from a cartridge. It is the reason you can't modify a rom for use with Sky3DS because that will break the encryption. They have to be pure dumps.

If you are on 9.2 or below, can generate the key for the template file and have two simple patches in the arm9 code then yes you can use e-shop games on Sky3DS.
Patch 1. remove Sig check
Patch 2. make sure it asks for encryption from the cartridge (reverse of what Gateway does).

it's .3DS version
around 2GB file size just like the normal size of the game
Even if they did, the mystery byte and everything is different and only sky people know to make it. The SHA1 won't even match

Also the ROM you're talking about was taken down and debunked
