Setting Up & Building Payload.bin, PS4 1.76 Payload Packets, a PS4 MemPatch Payload ELF and today PlayStation 4 developer MODDED_WARFARE shared a NetCat GUI for PlayStation 4 Payload injecting via the Webkit Playground with details below.

To quote: I just made a little tool for injecting payloads with netcat and thought someone on here might find a use for it. I'm sure some other people must of made something similar/better but all I could find was the batch file method.
It's pretty basic but does allow you to drag & drop your payload file into the tool and will also store your IP so that you don't need to type it in each time you open the program.
The application is packed but not obfuscated.
Thanks to @Modded Warfare and both @HydrogenNGU and @raedoob in the PSXHAX Shoutbox for the heads-up on this news!
