In my youth, I learned to recognize conditional JMP instructions by their opcodes and would bypass copy protection and nag screens all the time with CD 90, or explicit JMPs depending on how the code executed. I probably spent more time working on the crack than I ever did playing the games I'd patch, but I have no doubt that the practice is what inspired me to become a developer. It was so satisfying when I understood how a program worked at such a low level and I could get into the heads of the creators of those applications and games.
