my buddy and I are attempting to make our own guitar hero, and to do that you need a modded ps2. i definetely don't want to hard mod my system, so I'm looking at the swap magic. swap magic 3 is $19, which seems pretty good. it also comes with the slide tool (don't know what that is/what it does). anyway, is this a good option, or is there a better soft mod that is still fairly inexpensive?
