I know that a guy who called himself artifex made a proof of concept that the windows CE OS could run on the xbox.
The website about this project dissapeard.
The binaries are still available on the internet, but I couldn't locate a trace anymore of the sources that where used to create the CE image and the bootloader.
So, my question is, does anybody know where I could find those sources? Or maybe someone knows where I could contact artifex who started the project.
Windows CE should run at a normal speed on the xbox. I have it running on an Internet Appliance pc with 32MB ram and a 200 Mhz AMD processor. You can have the Embedded Visual C Ide for free from Microsoft. The Binaries you create can be distributed without copyright problems. Most programs designed for pocket PC's can be modified to run on a x86 CE system. (If you have the sources.)
regards.
