    Hey guys,
    Just wanted to know if it was possible to change/inject/extract certs ( headers ) from nsps the same way it is possible with xci file ?
    Thanks

    I think digital downloads are all the same. The authentication is all done on the server side. Meaning Nintendo don't need certs on it.

    I believe you mean to change headers of games. The cert is in the console.

    NSP do have certs, just unpack them and see. Also digital games have their own certs downloaded when leeching the ticket.
    It's not 3DS.

    Thanks for the replies, i mean the header identifying the games. I've been injecting my botw cert on a splatoon 2 dump i got from my friend's card. Meant to try the same with nsps cause i haven't been banned ever since. I know there is no guatantee but better than nothing. I don't see how to do that. Xci explorer allows it for xci files and it's called cert over there

    there is a way to convert xci to nsp i believe. you could perhaps use the same process and then convert.
    edit: this tool

    It won't convert the certificate into the ticket because they are two completely different formats. Tickets require certain data to be present in order to be forged such as Nintendo Account which cannot be found in the certificate making the conversion process impossible.

    EDIT: Forgot to mention the fact that certs are encrypted with Nintendo's personal 2048 character signing key so 4NXCI won't even be able to crack the cert to try to convert it ;)
