X-Box (non 360) Modding

I softmodded mine using Mechassault like on this video YouTube - How To Softmod Xbox

You're going to need an Action Replay and Ndure's Installer and one of the three games where you can use the exploit. They're the original Splinter Cell, Mechassault or 007 Agent Under Fire, and all of them have their own version of the installer so make sure you get the correct one one. Back when I did it you needed a specific version of the game as well, I'm not sure if the newer versions of the installer work on all versions of the games, though.

Once you have the Ndure Installer's save onto the memory card that comes with Action Replay you just copy it over like on the video, run Mechassault, then load up the save file and it'll reboot the console into the installer as seen on the video. After everything is intalled I'm guessing what you want is the Xbox Media Center to play all kinds of video files. It's really simple, I did it all in about 20 minutes. It was a long time ago but I think I can help you through it if you need.

Jam it back in, in the dark.

With the XBMC I'm pretty sure you can, haven't tried it since I don't have component cables for it though. I know for sure I've seen emulators on it that can do at least 720p.

There's nowhere I can't reach.
