If you have a 3DS running custom firmware (CFW), you can dump your Pokemon games and game updates yourself for use with the randomizer. This page will explain the various 3DS file formats, how to use game updates, and how to randomize your games for use on both emulator and real hardware. However, 3DS games are quite different from games on older Nintendo systems they can come in a variety of different formats, and they can be updated with downloadable patches. With v4.0, Universal Pokemon Randomizer ZX now supports randomizing all the mainline Pokemon games on the 3DS.
