Quick question. Is there a way to, as in softice, set a breakpoint on for example hmemcpy in Ollydebug? I am working on this target (BillPro) and I have cracked it already (really easy to patch) but to keygen it is more of a challenge for me as I haven't keygen'ed any app before. Therefore I have to follow the methods used in keygen tutes pretty close and the problem is that most are written for softice. As I don't have softice I was wondering if I could achieve similar results in ollydebug? I know how to set normal breakpoints on interesting calls etc. Thanks.

btw I recommend this target (BillPro) for newbies as it's quite a fun target and good learning experiance (well for complete newbies like me anyhow).

btw anyone here know a good board for discussing game protection cracking like starforce, tages, safedisk etc.?

Hallo cHeCksUm,

I don't know in which language is you target coded but try to use alternative breakpoints, such as GetWindowText, GetWindowTextLength, GetDlgItemText (Ctrl+N in OllyDbg).

If it's in Pascal/Delphi these breakpoints won't help you .

@ stealthFIGHTER

Thanks for the help. I will try it. The program is written in C so I guess it should work.
