I have an Xbox that I bought 3 years ago (pretty much when they first came out), that I use about once every 6 months. While at a friends house, he showed me his Xbox that was modded so he could copy games and stuff.
While I wasn’t really interested in the copying of games, some of the other things you can do looked interesting enough that I decided to see if I could do something like that without ruining my Xbox.
First up… for $59, I got an Xecuter 3 mod chip which comes with everything you need (except a soldering iron and solder).
I got mine from Mod Chip Man.
Much to my amazement, I soldered everything in correctly to the Xbox motherboard on my first try without ruining the board (it’s been 13 years since I’ve soldered anything).
Then I installed a replacement dashboard… For this I went with EvolutionX (also free).
I haven’t installed much stuff on the Xbox yet, but I did install Xbox Media Center… and all I can say is this one program alone is going to make me actually use my Xbox. It lets you manage your CDs and MP3s, etc. from your Xbox. It has network/Internet connectivity so it can also give you the latest news via RSS feeds, the weather for whatever cities you want and my favorite part… It can mount network volumes from other machines or access iTunes play lists via the network. All I can say is WOW. I would have done this years ago if I knew about it.
