 Posted: Mon Sep 30, 2013 7:51 am Post subject: Runtime JUMP Change via CE |
 |
|
Hi.
I am using CE for a long time. I mastered a lot of things reading tutorials and practicing. Still bad at LUA but improving. Also need more knowledge on AA. Thanks to all tutorial writers.
Anyway, I came across something I never needed before in CE because I would do it with other program or simply made my own. But now, I kinda want to learn to do it in CE.
"Problem" is this: Change the ASM jump command. It doesn't matter which one.
My example involves changing JNA to JA in CE disasm.
I tried with AA script (it worked) but then I had problems when reverting back.
So:
| Code: | target.exe+11322EF - 76 05 - jna target.exe+11322F6 // just needs to be JA 77
target.exe+11322F1 - 0F28 C1 - movaps xmm0,xmm1
target.exe+11322F4 - EB 08 - jmp target.exe+11322FE
target.exe+11322F6 - 0F2F D8 - comiss xmm3,xmm0 |
Now, I am quite sure CE can change this to JA without using AA. But as said, I never used it for this so I am kinda confused.
How to simply change this to JA with possibility to revert to JNA? I know that AA is needed for reverting so I guess script will do. Or maybe it doesn't.
Thank you.

Yes, I can change it manually in the disasm, But I was wondering is it possible to hotkey it somehow? There are few jumps that can be changed and it would be nice to be able to quickly deactivate JA to JNA (jbe, je).
I am guessing AA script is def needed but whenever I tried it, after deactivation I would get garbage code after the instruction. As said, I never changed jumps with AA.
I searched the forums for examples and made the working script but as said, after deactivation - 2lines of garbage code appear. I managed to get it without the garbage but then it wouldn't be deactivated...
Thanks for reply.

you can add a hotkey to your script file, so it activates or deactivates your patches, or you can add the address in the table then add a hotkey that sets the value at "target.exe+11322EF" to 0x0577 (JA patch)
then another key to disable(set value to 0x0576).

Cheers mate, it works flawlessly 
Tried with multiple same and different jumps at the same time. All activate/deactivate properly when proper byte patch is set.
TY!
