overview of the OMSK App, How to Install PS4 OMSK on 1.76 consoles and an updated Kernel_Hooks.elf that supports loading games and homebrew from USB... put them together to form Voltron and we now have a fixed payload from PlayStation 4 developer @ZeraTron on Twitter that allows loading two PS4 game backups!

From his Tweets below, to quote: Allow you to load 2 backups, one in OMSK, and second on Playroom. set them up like that /data/CUSA0010 and CUSA00200.
Playroom will boot CUSA00100 and OMSK CUSA00200.
Cheers to @B7U3 C50SS for the heads-up in the PSXHAX Shoutbox this early morning!
