Woow, thanks all!
I had no idea how much you guys are into XBox modding.
Zetr0, great work there with soldering. I'm afraid I am not that good at it and I don't have good tools, so that option is out of question for me.
I do have one of the games that will allow softmode, but I don't have AR. Do I have to have only software or I need software + hardware? Will just any memory stick work??
The way I understood, I should first soft mode my original HD, then after I get the key, I can open X-Box, place bigger HD and install back softmoded menu and eventually AID?!
Again, thank you all for the input.
