Yeah, I can train them in Gen 4. I just have to get my HG version's FC.
And I would really like to learn how to 4th gen RNG. The only thing I don't really get is delay and how to find it.
Is it possible to do it on a 3DS? Because my DS Lite's L button is screwed up and its really hard to soft reset on it.
EDIT: Oh wait, I forgot. My HG version isn't able to connect with the wifi where I live. Sorry...:(
I could still train them in 5th gen if you want.
