 Forums >>  Debuggers  >>  OllyDbg and Fraps?

Topic created on: March 27, 2008 11:52 CDT by Joelbenm .

Hi guys,

I'm trying to run fraps (the game recording application) in ollydbg, to see how it works, but it got stuck. i tried to search for the call IsDebuggerPresent (or something like that, the code is not in front of me now) to set there a breakpoint, but i think the freeze happens before

any tricks? i�m a complete newbie to ollydbg, so if you could pin-point me it would be just great.

thanks a lot for any idea,
Joel

fraps is packed with armadillo , so ill suggest you read up on unpacking and locate yourself either a tool or a tutorial on removing armadillo ..should teach you in the process how to use ollydbg aswelll

grt -thx. actually greg from ring3circus helped me - fraps is trying to fight ollydb using outdebugstringa. i replaced it with retn 4 and now it works!

but it is important to know about the packer - thx

Hey! Immunity Debugger has that format string patched :D

nicowow, can you please stop advertising ImmDbg every single chance you get? It's really annoying, to be honest. (Not to mention that ImmDbg is just Olly with Python and graphs, both of which have already been implemented with plugins. So much for a "powerful new way to reverse engineer"...)
