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.
