PS4Debug (A PS4 Debugging Payload)

This repository contains my custom version or fork of GiantPluto's FW 6.72 port of the ps4debug payload. I am the sole maintainer of this version and will be responsible for adding new features, pushing code improvements, fixes, etc.

A huge objective/goal is to make this PS4Debug Source Code firmware-agnostic, meaning that the ps4debug.bin payload compiled from this Source Code will be compatible with the following system firmwares: 5.05, 6.72, 7.02, 7.55, and 9.00. Eliminating the need of having 5 seperate source codes, one for each firmware version.

Recreating ctn123's Console Scan Feature

See Explaination + Code

Developer ctn123 described the console scan feature as essentially "Read memory, compare bytes, rinse, repeat," and I assume that once all process memory sections have been scanned, data is sent back. Based on this description, I've outlined a plan to replicate this functionality:

1. Memory Comparison: Allocate a buffer using the pfmalloc (malloc with prefaulting) function to hold a maximum of 10,000 (uint64_t-based) memory addresses. If the comparing function CompareProcScanValues succeeds, append the memory address to the buffer. Repeat this process until all memory sections of the process have been scanned.

2. Data Transmission: Once all memory sections have been scanned, loop through the array containing the uint64_t-based address values. Send back the addresses one by one using the net_send_data function until all valid addresses have been transmitted.

3. End Flag: Send back an end flag to mark the completion of data transmission.

Check out debugger/source/proc.c to view the current implementation of this feature.

See Usage Instructions

You need to send the value of 0xBDAA000D to the PS4Debug server if you want it to use the proc_console_scan_handle function instead of proc_scan_handle
