hi folks,
ive got a 16bit app and with w32dasm i can see the "badboy", but i cant see the "goodboy" in string references or just as ascii text. ive worked with a 16bit application never before. how to go on? do you got some tips (also english language) for me?
would bee nice.

if you see badboy jump then have a look why it jumps and how your code can get to this point (just like in 32bit).
if you revert all the jumps to not go to the jump to badjump, then either you come to an program error or ro goodjump

But using a debugger helps things a lot (at least for me)

How about: The app will never give you the 'Goodboy, you paid too much' messagebox. Maybe it will just continue registered when you manage to crack it.

The opposite does happen too, it always tells you the 'Goodboy, thank you so much' box. And after that, the app closes. It only checked the serial when it was run.

Guess you figured that part out

Grtz
