As near as I can tell, the only way to play imports on a PS2 machine is to actually mod the PS2. Can somebody give me a reccomendation on a cheap and/or easy way to do this? I have the model 3901 PS2 which I'm told is a difficult system to modify. I just want to play Bemani! I've got the official Konami Beatmania controllers and I'm dying here!

Also, is there a home version of KeyboardMania?
