The main jkpatch payload utilizes a port of CTurt's payload sdk (xvortex). This requires an environment variable PS4SDK pointing to your SDK. Alternatively, change the Makefile to have LIBPS4 point to the ps4-payload-sdk directory on your machine. I could have it referenced from the home directory but meh...

# change this to point to your ps4-payload-sdk directory
LIBPS4	:=	/home/John/ps4-payload-sdk/libPS4

If you decide to edit the resolve code in the kernel payload, make sure you do not mess with...

void resolve(uint64_t kernbase);

... as it is called from crt0.s. And changing this will produce errors.

See other branches for other kernel support. I will support latest publically exploited firmware on main branch.

See either Example.cs or look at the RPC documentation.

You can read/write memory, call functions, read/write kernel memory, and even load elfs.

Here is a cool example of an elf loaded into COD Ghosts (forge mod made by me!) You can download the source code to the forge mod here. Have fun!

• General code clean up and refactoring
• Hope to make standalone elf for FTPS4

You need to trigger the 4.55 FreeBSD BPF kernel exploit and send (netcat/socat) this file over your network, to your PS4s IP. Send the payload.bin to port 9020 and the kpayload.elf to 9023. Or simply replace the payload.bin and kpayload.elf in the app you're using (Memview, PS4 Trainer Utility, PS4 Cheater etc.).

I have personally configured Apache to use CGI scripts to automatically send these over when I navigate to a certain URL.

While running this payload, minimize the browser with the PS button to keep FTPS4 running in the background. I found it works best to close an application before opening a new one, when switching games. Otherwise there's a chance it may freeze and require a reboot.

Thank you to flatz, idc, zecoxao, hitodama, osdev.org, and anyone else I forgot!
