Does anyone else know about the cloning glitch in emerald? I use it plenty to clone my ho-oh and shiny Fearow, and people trade for them plenty. Its quite helpful.
If you don't know how to clone you just have a box with an open slot and make that box the active one. Then you have the Pokemon you want cloned in your party and go to the battle tower. Then save. Then deposit the Pokemon you wish to clone. Then save again. Now withdraw the Pokemon. Now go to the multi battle lady(far right). Enter with any Pokemon. When she asks If its okay to save say yes. You should notice a gap between that and the next message. Shut your system off, then turn it back on. You should have the Pokemon in both the box and your party. (I have heard that if you do this consecutively you will lose all the clones, so go outside and save when you turn it back on. Also trade a clone off to another game, as anything can happen at any time.)
