Using a hard modded or soft modded Xbox, you can load games and applications off the hard drive. However, much like the PS2, you'll want to upgrade the hard drive. Which is a bit more difficult than on the PS2.
i heard there's other operating systems for xbox like unleashX or sth. So i need them to load games from HDD ? And how do i copy my back up games onto my HDD ?
UnleashX is a hacked dashboard based on the original MS Dashboard. I have no idea what sth is...
Like I said before, you have to have a modified Xbox. A hacked dashboard is then used to launch homebrew and games from the hard drive, as well as many other tasks.
To back-up games to the hard drive, you should use dvd2xbox.
I agree, not a fan of ps2, havnt touched mine in for ever, i use my xbox,soft modded with unleashx+ndure, i find it really simple to softmod and upgrade the hd in the xbox, pretty simple to use
