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.
http://code.google.com/p/ir-gts/ is the download link. Download that, and also Python if you don't have it installed (programming language, like Java).
Run the script in that download. It'll tell you what your computer's IP address is. Go into the Nintendo WFC Wireless Settings on your cartridge and change 'Auto-obtain DNS' to whatever it tells you to; this will then make your DS connect to your computer instead of the Nintendo servers. From there, just connect to the GTS, it'll reach your computer instead, and upload files using the script. Note that they never leave your cart, you just send the file then get a 'cannot be traded!' error message, so you don't lose any happiness or what not. To download a 'mon, queue it up using the script, then connect and you'll get a copy of it.
No problem on the clone, and everyone's gotta start somewhere =).
You should look into using IR-GTS for cloning, though. Takes a bit, but it's pretty easy and you don't need any outside tools, just a computer, a DS and a wireless router.
Okay, give me a couple minutes to get this Mewtwo cloned and I'll be back in. Takes a while doing it this way, cause you've gotta connect and reconnect like three times.
I can't seem to find the Moxie Adamant Sandile... I can get you all the others but i can't find that one. =/ add the fcs i said about on my wall post please.
