Hi guys,

I've got a game someone has written here - it's a Windows .EXE file, and
from the contents it is obviously written in some variant of C++. Can anyome
reccomend a decompiler? I'm just interested in a single routine from the
exe - a checksum generation routine. I already know that the .exe has enough
debug info to name the checksum generation routine for me. I'm not looking
for compilable C++, or even pure C... Half C and half assembler is fine with
me. I'm just looking for something more readable than assembler (because I
don't know assembler very well).

Cheers,
Nicholas Sherlock

What good would that be, other than cracking the software protection?
Write you're own game instead of wasting your time with illegal stuff.
Reverse engineering and decompiling is usually not allowed - otherwise
the program would be open source, wouldn't it?

Try SoftIce.

And learn assembly. You can't do reverse engineering without it.

How about turning a hamburger back into a cow?

Yes, but that is not describing the situation.
A binary executable program _can_ be turned into source
but the probability of it looking like the original is
very low.

Search the newsgroup for the terms "decompiler" and
"reverse engineering". I've answered this issue
too many times.

Same for the cow. Except, maybe the probability is a little bit lower.
Though, if you've had the time... and appropriate tools...

cheers!

Given cloning your chances of getting something back from the hamburger
that looks like the original cow is perhaps better than decompiling!

How would a checksum be involved in software protection? This game does not
have any copy protection. I'm trying to generate files to be used by the
game (In this case, allowing the user to generate "dog" characters to insert
into their game).

Thanks, looks like I'll be learning assembler..
