Thanks for the answer but actually I see no need for it in this cIOS (the dev thingy) I was just curious if it would work and if it was easily implemented it also could have been added at the same time as the Korean common key "just becaouse we could!"damysteryman said:@IceIceBird
Kinda, but not really. I did try that once, but I had to edit the wad (I was trying to install a dev-only channel, the Disc Check wad). Dev stuff not only uses a different key, but also uses different certs too. And in order to even use the 2nd key, byte 0x1f1 in the ticket must = 0x01, and only Korean titles have that.
In the end, to get it to work, I had to decrypt the wad with the dev-key, then switch out the dev certs with the retail ones, then reencrypt it with the common key, then install it normally.
(But maybe we should add the dev comman key also when we're at it? Who knows.. maybe someone makes an wad installer or mod that could do the above you explained or vice versa. Maybe better to suport it either way for future projects?
