Hello all, first post;

im trying to run code when a routine is called (Ingame Menu), when i press the button it goes from 00--01 and thats when i want my code to execute (and not delete itself)

right now i have:
Code:

alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

newmem:
pushes into function, then calls it 

originalcode:
need help here

exit:
jmp returnhere

menu address:
jmp newmem
returnhere:


using memory view it looks like:
(not pressed) address = x, bytes = 00 00, Opcode = add [eax],al
(pressed) address = x, bytes = 01 00, Opcode = add [eax],eax

what would i put in "original code:" ?

the original bytes of the instructions ad "menu address" that you overwrite with the 5 byte jmp

If you use the code injection template this will be done for you
