Search Google or write some DLL file to tell Windows Explorer to not include the copy, paste, etc. commands or just to disable right-clicking on this particular file.

ahm... what does copy protection mean for you? there are several systems which

a) generate a password which has to be typed in before gamestart
b) add somethin in the cd image so that the cd/dvd cannot be copied any more

both systems are available for free, google for it or search @ downloads.com

i guess there is and there will be no way to do that. imagine. it would be like a virus-you cannot move it, only execute and delete. how would you ever be able to distribute it without moving it? peculiar idea...

That's just the thing about software. Almost anyone could copy it and it's just the matter of clicking the file, holding the control key pressing C then V and you have a duplicate. Repeat a dozen times and you have thousands of duplicates. Encryption makes it very difficult to actually "steal" the contents of the file. Together with file compression, it makes it even more difficult. Think of it in that no one could steal your art unless they are so serious they write a program to try and detect the key, of which could take weeks, even months of constant CPU power on 128-bit encyrption. The computer has to cycle through 3.4E38 possible combinations just to break the key.

Not to mention the fact that by specifically disallowing someon who legaly bought your game to not copy it (re: back it up) to a CD, you are, effectively, screwing them out of one of their basic consumer rights (they *might* be able to actually sue you for doing that too...not sure though).

IMHO, "copy protection" is nigh-pointless. It punishes the people who support you buy buying your product. EVERY copy protection scheme out there can be broken. Software, hardware, etc. For me, I'd just use a simple password...and a resonably priced product. Not much point in putting a lot of time and money into some near useless copy protection scheme. If someone wants to pirate/crack it, they will...no matter what I do. I think the key is to reward those who have bought the product, rather than to try and stop those who haven't.

My 2¢ anyway.

Armadillo has an option for hardware locking. I'm not sure if this will suit your needs, but you should look into it.

Hi!

A good copyprotection is the evaluation of a registration key via internet.
The most games today need access to the internet - so this isn't unusual today.
If you track the license-keys you can easy recognise illegal codes (because they are very often used).



Just look at microsoft's XP-Keys. You can run a kracked XP but you will not get any updates...

It's impossible to keep someone from copying your files (unless microsoft were to implement a system that dissalows the reading of certain files, in which you'd have to have every file like that specially certified).

You're not going to be able to stop people from coppying/cracking. The best way to do it is like Mercuryus sayed, create an algorithm for cd keys, and then have it check if it's been used via the internet. You should also hide the source files for your project with a packer like Molebox, or whatever the were talking about earlier.
