Remote Memory Debugger

Small project written to help search for and change memory values in games.

Server runs on a PC and can be connected to over Netcat etc.

This doesn't work at the moment.


remote_debugger     # start the debugger on the local machine with a local CLI
remote_debugger -n  # start the debugger with a udp server

By default the remote_debugger runs on port 4444 and uses UDP

To connect to it you can use netcat, i.e.

nc64 localhost 4444 -u -vv


  1. Get it working - can only modify own process (i.e. the debugger!), might be permissions
  2. Convert from hex on the mm (memory modify) command
  3. Testing

The search transaction id is needed to refine the search so don't lose it

Listing the search results

lsr 4347

You can keep track by using the monitor command

        0x00100160 = 0x00000001 (1)
        0x0038B25C = 0x00000001 (1)
        0x0038F398 = 0x00000001 (1)
x to exit, others to contine

Modifying a value

mm 1520,1048928,4,0
Memory modified OK: 0x00100160 to 0x00000000

Yes, you need to convert from hex (addr) to dec.

We can now check it worked with the monitor

    0x00100160 = 0x00000000 (0)
    0x0038B25C = 0x00000001 (1)
    0x0038F398 = 0x00000001 (1)
