How do you clone a Pokemon in the blue version?

Answer 1

When you have a Pokemon you want copied, go to your computer, into Bill's PC, and open a new box. Put the Pokemon you want into copy into that box. Then click on the switch boxes and after it says it will save when you switch boxes say yes. Now timing is key, click a different empty box and before it switches, turn off the game. You will now have two of the same Pokemon for yourself!

I've done it on red blue and yellow version when these games came out. it does work and does nothing to your game. same as cloning items.

P.S. this can also destroy your file if the game catches you repeating this.

if you really want to take the risk. its up to you
