Hello again, still chipping away at DOOM2 for dosbox.exe on steam, I've got a moderate inf-ammo working consistently right now using threads, and I'm still working on more.

Currently I'm working on movement changing cheats, and have been unable to create an AOBinjection (I'm not sure if there's another way btw) that properly replaces the bytecodes.

My jmp 'location' bytes are incompatible with the following:

Code:

144DDF39 - 8B 15 EC116D00 - mov edx,[dosbox.exe+2D11EC] { (1) }

Such ends up ruining the routine functions by inserting extra bytes before the jump and/or modifying unnecessary bytes.

How should I set about rectifying this?

The default AOBinjection module offers the following yet also is incompatible.

Code:

INJECT+05:
jmp newmem
nop

Attached are pictures to further display the issue.
The first is the jmp implementation.
The second is modified, but simply labeled.
The last is the unmodified function.
