First thing's first, I didn't come up with this technique, and there is a good chance that if you don't know what you're doing, or you mess up in some way (hey, accidents happen) that you may end up losing your Xbox completely. You have been warned, do this at your own risk, if you mess up, its not my fault, or the fault of the person who thought of this.
Another thing to consider is the cost of this venture. If you already have an Xbox, it will cost around $45 in materials to put the mod onto the Xbox. Thats if you buy everything brand new, if you buy it used, you can probably get everything for $10ish.
I am not going to explain step by step detail on the process, because I found out about it from this website:
http://www.productwiki.com/microsoft-xbox/article/how-to-go-from-
xbox-to-xbox-media-center-in-30-minutes.html
Here is a list of the materials you will need:
- Microsoft Xbox ($150)
- Networked PC Computer ($???)
- Original MechAssault game ($20)
- Datel Xbox Action Replay ($25)
- Krayzie's NDURE installer ($0)
- Xbox Media Center (XBMC) ($0)
- uTorrent ($0)
- FlashFXP ($0)
- Winrar ($0)
I'm not much of a cut and paster, and besides, I don't want to generalize on a very complicated process, so visit the Product wiki website and follow their instructions to the letter.
