 |
|
Got the operands at: http://x86.renejeschke.de/html/file_module_x86_id_26.html
Cheat Engine seems to be able to read the Far Jump operand properly, but fails at writing it aswell.
The major problems come when it tries to read any Far Calls, it lists the right pointer, but the instructions appear bugged.

Yeah, it's currently not implemented. Use
| Code: |
db 9a
Dd address
Dw segment
|
If you really need to use it.
For general use i don't recommend using this though unless you are absutely sure of what you are doing. (E.g executing 64 bit code in a 32 bit process running on 64 bit windows)
But honestly, unless you have modified the GDT this will just cause access violation errors

I thought of using it for making my own binary payloads for a game, but I guess I'll just use push eax; mov eax, address; jmp eax; pop eax; if this instruction can cause problems.

You can also do:
| Code: |
Jmp [addresswithnewaddress]
addresswithnewaddress:
DD address
