I have a few questions on emulators. I've heard loads of talk about "save states", which I'm pretty sure are an option on emulators. But, what is the standard DS emulator that most people use? And where do you get games for emulators? Also, if I were to run, say, Emerald on an emulator, would I be able to PalPark the pokémon I catch onto my Diamond or HeartGold carts, or would I need a middle-man GBA cart? Similarly, if I were to run SS on an emulator, would I be able to trade to my current DS games? If so, how?
Also, would I be able to play Wi-Fi battles through an emulator?
If anyone can answer some of these questions, or link me to an FAQ or something, I'd greatly appreciate it.
EDIT: @the guy above me: IV abuse is easy. If you have a flawless ditto, then try using the seed 7C08023F. On frame 2 of that seed, the spread is 3x B inheritance, 3x 31, giving you a hexflawless egg if the B parent is flawless. Basically all you need to do is hit your seed and immediately talk to the old man, since you'll likely start around frame 2. It might take you a few tries, but I found it relatively easy to hit with the help of PikaTimer
