PS5Debug

Warning

The code is probably a mess, sorry... also I suck at documentation so you get what you get lol

Info

This has some slight API changes from ps4debug, but not a lot, and most things should still function like normal.

Because of the lack of time to work on things, ill be open sourcing this un-finished, and would love community contributions

Right now this is built using the ps5-payload-sdk, and will build as an elf that needs to be loaded through an elf loader... will probably change that eventually so it can run standalone if a user wants (untested on HEN-V)

Unfinished Items

  • Debugger has a lot of issues, it needs finished
  • proc_scan_compareValues needs done
  • proc_scan_getSizeOfValueType needs done
  • proc_scan_handle needs done

New Commands

  • Unload 
    Command to kill the payload
Command: 0xBD0000FF
No payload packet needed
  • Process Base
    • Command to return the base address for a process
    • Command: 0xBDAA000D 
      struct cmd_proc_base_packet {
    uint32_t pid;
} __attribute__((packed));
#define CMD_PROC_BASE_PACKET_SIZE 4

Current Tested Features

  • Console Commands
    • Reboot
    • Print
    • Notify
    • Unload (New)
    • Version
  • Kernel Commands
    • Kernel Base
    • Read Memory
    • Write Memory
  • Process Commands
    • Process Base (New)
    • Process List
    • Read Memory
    • Write Memory
    • VM Maps
    • Allocate (r/w only by default)
    • Protect (ignores length, and sets a protection level of 0x7 to the entire map in the vm_entry)
    • InstallRPC (this is faked right now, as its not actually needed, it will return a bogus address)
    • Call (Takes a rpcstub but ignores it, as it uses ptrace to do calls now)
    • Free (idk if this actually does anyting?)
    • Info
    • Load Elf (needs to be updated, using a ptrace elfloader that kind of soft locks the game sometimes)
  • Debugger
    • I think most of its broken right now lol, someone that knows more about ptrace and debuggers than me could probably fix it pretty quick, its mostly a copy paste of the ps4 code right now

Changes Required

  • The elf loader needs to be re made, and more specific to loading an elf into a game, it has a slightly modified version now, but I think more needs to be done
  • Maybe find an alternative to the free method? (idk if it even does anything right now)
  • Maybe find an alternative to the protect method? (so we can protect certain addresses, and not the entire vm_entry)
  • We don't need to use sceNetSocket functions, should probably move awy from that, but for now it was easier to replicate with it

How to build

Follow the instructions for the ps5-payload-sdk I believe the only additional library needed is libSceNet.sprx The just run make

Credits

This is a really important section, this project would not have been doable without the foundation work of a lot of really smart people.

  • Big credit to astrelsky with all his work on HEN-V and for process read / write code, as well as many other things
  • Big credit to John Tornblom for his ps5-payload-sdk, as well as the sample elf loader I am using
  • Credit to SiSTRo for the idea on how to set a protection level
  • And of course, credit to golden for the original ps4debug... where most of this code was grabbed from.
