On a modded PS2 and Wii you can play games directly from iso images.
This can also be done a Xbox. You just need some tools, some attach/default.xbe's the correct bioses and some dashboards.
I have tried to follow a tread on xbmc4xbox and another one on emuxtras on how to do this. But I gave up as it was
unclear to me where to get hold of the attach.xbe file and also if i had to re-flash my bios to make this work.
I wonder if someone here can make a good tutorial on how to make this work.
( I use xbmc4gamers as my main dash, And i have two xboxes, one with evox m8+ and one with indbios 5004. )
Thanks,
