In the XBOX you can save your own music to the hard drive, then play it in any game you like.

Wrong. Although you can upload music into the XBox hard drive, you cannot play it in "any game that you like." The only games that would allow you to play them in are the ones that have the options to. I don't think MK Deception will have an option to play your own music during the game.
Peace.

Haha, that'd actually be a nice addition. Playing a death-like game and killing someone while Jessica Simpson sings her pretty little heart out in the background.

Heh.

I don't think this will be an option.

That would be sweet. Id be bumpin some cradle of filth.

im sure they said u could do this.. how do u upload music?

It's possible, don't let these people shatter your dreams. You can play any music to any system you want(I think), you just gotta re-wire some stuff. I have a friend that does this with his PS2, I just don't know how. You're gonna have to look up illegal ways to do it, I don't think there's anything official about it..well atleast for PS2.

Oh but if you're talking about uploading music, then i'm sorry I responded. I was talking about re-wiring a PS2 to a stereo system so you can pop in a cd and not have to listen to their music.

That's cool thanks man but I don't wanna mess up my playstation or xbox.

Yea, it's not how it seems though. You're not gonna take apart your PS2, it's more of connecting the two things. And no problem, I didn't think it could be done till my friend had his cd playing during Gran Turismo.

I was thinking the same thing. That would rock, especially putting some Manson's Fight song in the background
