But then this should work with homebrew as well, shouldn't it? Since homebrew stuff is also DRM-free. That's what I don't understand. If you can just do that, why is there still no soft-mod for the 360?
Also, this method does not work with the demo linked to above, because it's modified. So there is apparently some kind of DRM still, which breaks as soon as you change something. So "DRM-free" doesn't seem right to me.
ps: I did mod save game files myself already. But save games are not executable code.
