Unfortunately, the process of getting these levels to your system are a bit cumbersome. Provided you have some external USB memory card/stick (the PSP works well in this situation), you'll be able to transfer the files to your system. Be warned, however. You'll have to follow a specific directory layout in order to get this new level onto your machine. Hopefully, a more elegant in-game solution will be made available in the future.
