If you need help collecting CD's, this is the comment you're looking for. Go to stagebuilder and make a new stage. Make blocks on the outer rim of the screen (except the top) erase the top two blocks on the left and right sides. Now put conveyer belts on the top left and right blocks so if there's a CD on top it'll come down. Now make conveyer belts on the bottom leaving a space in the middle (so the CD's will come to the middle). Then the stage is done. Now fight with another human player (but no one will play as that person) on that stage. Set the items to high and only to the sandbag. The time is unlimited. Keep hitting the sandbags until a CD pops out and it comes right to you (just make sure you're in the middle of the stage. I hope this helped.
