DARK-MAN-X, По поводу ограничений следующее сказано:
"There are still lots of limitations (no kernel mode, prx should be less than 5MB, no static elf support,…), but tools are being progressively built to make this easier, so I’m sure that as I type this, more convenient tools will already be available. I spotted some tools that allow to sign static elfs by embedding a loader inside of the eboot".
