First, you need a GBA and Sapphire/Ruby/FireRed/LeafGreen.
You also need the GC and GBA cable.
Beat the game and go to the trading center in Phenac City. Take the Pokemon you want to duplicate and trade it to Pokemon Colosseum. This may be a little risky, so make sure you can still live if the data gets erased. Right before the game saves, turn off the GBA. If it was successful, then you should have 2 of the same Pokemon.

As for the question, there really aren't any duplication cheats besides the one on Colosseum, and I really don't trust it.
