Pokemon and Item Cloning:
Select the pokemon that you want to clone. Give it any items needed too. Put it in any of your boxes. Now, go to the GTS. Talk to the lady and enter. Put up a pokemon for trade (NOTE: Try this with a low-level pokemon who doesn't have an important item first). When it takes you to the loading screen, watch the little clock on the bottom-right part of the screen. Count how many times it hits the top, and note where it was when the pokemon was uploaded. Go back to the summary screen, and take out the pokemon. Once again, watch the clock. Most people's clock stops moving between 7.5 and 8 rotations.
Now, put the pokemon that you want to duplicate up for trade. Right before the clock gets to the interval where it changes, turn off the DS. Turn it back on, and load the game. You will probably get the error screen, but don't worry. Continue to load the game, and go back to the GTS. If you performed the glitch correctly, the pokemon will still be up for trade. Take it back, and leave. Now, go to the PC to the left of the counter. Load it up, and check your boxes. If you performed the glitch right, you will have duplicates of the pokemon (and possibly item) that you tried to clone.
If you didn't get it, try, try again. It took me about 13 times to get it. Just keep trying.
NOTE: This glitch is very risky. Several GameFAQs members have reported it to screw up their game. Several other members reported their pokemon being traded before they could get back to it. Though the number is very small (about 3/100 people), it still is a risk. Don't say you haven't been warned. To prevent the second problem from happening, request an evolved pokemon that is level 9 or lower (eg. Infernape).

How to catch Regigigas:
First, you need to have the national pokedex, this is obtained by seeing (not catching) all 150 sinnoh pokedex pokemon. Second, you must have access to snowpoint temple in snowpoint city (if you have the national pokedex, this shouldn't be a problem). And third, you need to have regice, registeel, and regirock, which can only be obtained through pal park from the ruby/sapphire/emerald games or by using a cheating device. If you have met all these conditions (make sure to have regice, registeel and regirock in your party), then navigate the snowpoint temple (just a sliding puzzle with ice, a pokemon staple) and regigigas will be waiting for you at the bottom floor. He will be at level 70, and he will have the ability "slow start" (his atk. and speed are cut in half for 5 turns). Make sure to hit him hard and fast before the five turns are up. Try to paralyze regigigas and catch him with an ultra ball, you'll want to save your master ball for another pokemon that runs, like mespirit or cresslia.

To clone pokemon without wi-fi put a ditto in the daycare and send the pokemon you wanna clone to the day care too. (it works on all pokemon with GENDERS except legendaries) even if the pokemon dont like each other they'll still lay an egg. What ever pokemon you put in the day care with ditto the unevolved form (or the same pokemon) will hatch from the egg.

How to catch cresselia/mesprit:
If you have cresselia and mesprit running around sinnoh, this is for you. First, migrate wobblefett from leaf green, fire red, ruby, saphire, or emerald. Next go to tunback cave and catch brongzong. Then find either mesprit or cresselia. Have wobblefett out first no matter what level. His ability should hold the pokemon in battle. Weaken the opposing pokemon. Switch wobblefett with brongzong. Use block. Bronzong should know it. Then use an ultra ball. It should catch it. If it doesn't, keep trying. Make sure it's health is low. Then capture it.
