I've copied an original MechAssault to my xbox harddisk, and it reboots my box after loading 1/2 way. Anyone seen this? I'm using EvoX.

What bios are you running. You might need to update your bios to the latest and greatest. I recommend the one in my sig..

For what it's worth, I was running evox 2.5(a slightly older bios) and copied mech assault to my hd and it ran fine, even with IGR turned on and all. It might be worth turning off your IGR's in evolutionx(if that's the dash you're using), but after that, I'd say just try recopying the game onto your HD. Last I knew, mech assault didn't need any patching, so I'm guessing some files just got miscopied.
