Hello PSXHAX Members, today PS4 Developer Zecoxao shared a new PlayStation 4 tutorial proceeding his PS4 Version Spoof covering reading and writing to the PS4 process memory using proc_rwmem for those on a 1.76 Firmware console.

Previously, Peek and Poke support was added to PS4Link by PS4 Developer psxdev (Big Boss). This nice addition helps out to Read and Write to the PlayStation 4 process memory using the function "proc_rwmem".

The original credits goes to Wskeu and Wildcard, these individuals did the reading part and writing part of this tutorial you are about to read.

To roughly quote Zecoxao's tutorial: How to read and write to process memory using proc_rwmem

Credits (these go first):

Original authors: wskeu (for the reading part), and wildcard (for the writing part)


1. Compile the payload. Specifically to what you want to patch, the size, etc. So, this:

/* set variables for reading and writing mem */
size_t dumphexsize = 0x200;
size_t dumpsize = 0x1; // size that you want to read
size_t writesize = 0x1; // size of the data you are overwriting
uint64_t base = start[0]; // use the number of the mapping you want to write to, starting with 0
size_t intoBase = 0x465FC9; // relative position of base
and this:
char *target = "SceShellCore";
2. Load elf-loader. Let it stabilize on stage 5. (To increase success rate, clear cookies, cache and history)

3. Load the payload. Specifically:
socat - TCP:my.ps4.ip:5052

socat -u FILE:path/to/rwmem TCP:my.ps4.ip:5053
4. This payload will take a while to listen to logs. Be patient. After a while it’ll show log output with the memory before and memory after.

Notes: This is process Peek and Poke (reading and writing to process memory) using proc_rwmem, which is more efficient than the old method.
