Protect Your Games & Software by putting a serial number protection application at the start of your game or software.

This will ask for a code before you get to the game or software.

This is recommended for commercial games.

This would be the easiest time of program to crack if it should use this method of serial codes. When a cracker uses a debugger he'd just have to put a break at the api, or the section of code that does the compare of values. Once he does that, do a single step through the code and your password/serial would be in plain text when it reaches the compare instruction. Wouldn't be hard to open the file in a text editor and grab out the plain text password.

Your generated serial is copied to the clipboard

Do you need a complete FPS,3rdPS engine ?? Or a collision command libary?? well here it is:

The best way to figure out how to do serial codes is to only ask for the code from the dc packet once - then store it into the windows registry. This means the serial code is stored inside the windows folder, and does not need entering every time.

have a look at some of the threads on protecting your code, there's some good advice, and it also explains the pitfalls of each one.

i know this is a little off topic but not by much. does an1 remember the good old days in DOS when u had to enter a word off a page that was given during startup just so u could play it. get it wrong 3 times and it exited back to DOS.

y don't they ever do that again. would make it harder to bypass. and lets say the game knew what day it was and found out it was friday the 13th. so it asks u to type in a whole paragraph just to annoy u? i know its not a good idea that but me and my mate were on about it earlier and we had a good joke over it

I remember Basically, if you didn't have the manual. you couldn't play it. These days it's so cheap (or free) and easy to copy manuals it wouldn't work. There would be a PDF version on Kazaa within days.

I seem to recall they used that in Sam & Max Hit the Road.
