Overview

My original intent was to implement a minimalistic strategy that could lead to running stuff like fselfs and debug pkgs. I don't like methods that do a lot of patching and involve a lot of manual work, so I prefer to use built-in functionality whenever possible. While the result is not as minimalistic, it is effective. As I've said multiple times, this stuff can be ported to any firmware.

So here's the problems we have:

1. Executable files including SELFs/SPRXs/SEXEs/SDLLs are signed and encrypted. While their fake versions are not signed and encrypted, we usually can't use them on a retail console due to restrictions that are put in place by the auth manager that loads them (a secure module, or SM, that is running by SAMU, a secure co-processor that is embedded into our AMD's APU). The (S)ELF loader from the kernel use SAMU calls for everything crypto-related...
