Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Yea, So far I've caught all grass catchable pokemon up to route 8. Just got on route 8 and on a catch/train spree. Y version I'm blowing through it without doing all the catching and mass training.
I'm not sure. I know the 3ds has updated way past the version that action replay has right now to the point where I have to use my dslite to use it. But I'm still unsure about hacks.
