Hello Just wanted to say hi I am new to these forums and was wondering if someone could help me out a bit. I have a jtag xbox 360 not the slim. It's been collecting dust for about a year since it was jtag'd and now I am curious to get back into the gaming scene with it. I saw this FreeStyle Dash 3 and wanted to know how I go about installing it on my box? Are there any other softwares I need to do the installation or just download F3? Cause I also seen something called Dash Launch 3.0.3 is that something I need first? If so how do I install that as well? I know my jtag has Xell 1.1 I think lol it's pretty old. Thanks in advance.
