Here you find Version 2.25 and 2.26 for Download.


It's a little sad that the original page has disappeared however it's still in the internet archive:
http://bit.do/dUP


Hmm well patcher is pretty self explaining and yep you need to know about reverse engineering else it'll be a whole book to write about Ollydebug and finding and creating patch patterns. (But you may ask some specific question ich ya feel so.)

One nice thing about dup2 is that you can open a created patch.exe and load it again as project. This decompiling supports was removed in v2.26.

However you can still open Patch exe created with v2.26 in v2.25.
Here is how to do this:
  1. Run the patch
  2. Get %temp%\dup2patcher.dll
  3. (Unpack it)
  4. Test it via rundll32.exe dup2patcher.dll,load_patcher

Now You may copy the .rsrc to some v2.25-patch exe
OR
Transform the dll into exe in PE-Header Change
  1. PE- Characteristics: 0x2102 -> 0x0102 ( DLL )
  2. AddressOfEntryPoint: 0x000020D0 -> 0x000020F9 (<- Export: load_patcher)
  3. (Change Extension: *.dll -> *.exe )

Now you can open the patch file in dUP2.25.

So now happy reviewing/improving ya's and other's patches Big Grin

Attention the transformed dll to exe has two flaws.
1. GetModuleHandleA(0x0) is not set so Dialog may look strange
2. ExitProcess is missing so exe don't really quits (you'll need to kill it in the Taskmanager)

Recommended tools: LordPE(<-is inside myTools), Restorator 2009 (4.00)
