Err, what was the upshot of this?

On a similar note I tried to use my Japanese Sapphire in conjunction with Colosseum, and the result was a catastrophic failure. Well, not catastrophic... but definately failure. This was just using the battle-colosseum feature. I haven't unlocked trading yet. As trading with Story Mode involves different principles (I hope) to registering, will my Japanese game be compatable with that? Or am I getting it in the shorts again?
