I want to set a conditional breakpoint if the register is an unicode like 'm' or 'a' or '2' using ollydbg.

How can i do that ?

I have the latest version of Ollydbg '2.01'. OllyStepNSearch plugin is used for this case but it is not compatible with the above version of Olly.

Thanks for your help!

    What keeps you from using the Ollydbg version where this plugin is compatible?

    OllyDbg has conditional breakpoint capabilities, have you tried that first?

I'd suggest you use OllyDBG version 1.10 (non-plugin) or Other edition like odbgSND.

You can use Conditional BP with below grammar:

UNICODE [EAX]=="HamiD a.k.a AHA"

OllyDbg treats EAX as a pointer to UNICODE string, converts it to ASCII and compares with text constant. If you want the Unicode value of the register must be written as the following conditions:

EAX == 75007500

This condition is triggered if the value of EAX equal uu Unicode.


Check these out :



And here is two conditions I recently used in Olly:

([UNICODE[esp+10]] !="BAR") && ([UNICODE[esp]] =="FOO")
[[STRING[esp+8]] =="FOO"] && [[STRING[esp+4]] !="BAR"]
