Cheating in Pokemon games, nay or yay?

I only ever played the original Red & Blue, but fuck Nintendo if they thought everyone was going to buy two games or whatever and play through the full game twice to get all the pokemon exclusive to Red or Blue all onto the same save file.
My friends and I used the glitch to copy traded pokemon instead of actually trading them, and I'm proud of it!
I think that was actually the first hack/glitch/exploit I've even used, and it's not something I do often. But yeah...nah. Not happening.
