That's correct. SKY3DS is for playing ROMs of retail games; pure and simple. If you want to be able to play eShop titles if suggest you consider gateway instead.So just normal retail roms
Has anyone tried to run one of BBB's eshop dumps? They're packed using retail encryption. Could work on Sky3DS...
The used signature process uses asymmetric keys, so even if you can decrypt it, you cannot re-encrypt it back if you modified the content. If that was that simple it would be pretty easy to decrypt 3DS ROMs from your PC... Unfortunately it's not.
Rom encryption uses symmetric 128bit AES CTR keys, thus the XORpads. As I said; the problem is the rsa signatures aren't properly signed.
No, they are not. These dumps are decrypted (signed with 00 key). If they were encrypted using retail encryption it would be possible to sign homebrew code and run it on Sky3DS.
