Bluedump.
I don't care if you don't want to use it, it's the easiest and best Method. You could also try to make a full FS/BootMii-Dump, and pack it into a .wad with ShowMiiWads. Though, if you do that, there's no need to make it into a .wad, because you can then just extract the .apps...
(And sorry...I'm not shure if you manage to make your own cIOSCORP, if you already fail here...not to be rude, but maybe you should just leave it...)
