Yes, you do. If you own an R4 card, there's a mechanism in which you can transfer the save file onto your memory stick so you can play it. Alternatively, you could load up the pokemon file with pokesav and it should have your pokemon on it - this method requires an AR.
There might be other methods nowadays - like uploading it onto a trade link via an internet connection and trading it that way, but I've been out of the scene for far too long to know lol
Hmmmm question - if you RMG with an emulator, don't you need to have separate machinery to transfer it to your cartridge? O.o The only time I ever used an emulator was when I was just playing for fun on the computer so sorry for my ignorance Dx
"Can you breed or catch or both in 5th gen?! And ID/SID abuse too?" - Yep xD I'm trying my hand at Breeding in 5th Gen (haven't done that before) - but I can do all those things in both 4th and 5th Gen. Not much of a big deal here, many people can RNG on Smogon xD And it's great that you battle with interesting teams on PO - they put too much hype on OU standards and that xD
Ahaha! Congratulations!!! :) I'm so happy for you ^^
Umm - I haven't played :( I've been so swamped with work and friends. Summer means a great deal of leisure for me so yeah...I'll get back into it soon though! Just haven't had any interesting team hit me yet :/
