Attention, this is a well known evolution-x Bug, yes BUG.
When does this Bug Occur?
When you have your network cable plugged when you started evox with power on, the next application using the network will
hang up. That is 100% your problem, not anything else.
Why does it do this?
Because team evolution-x has somehow managed to not shutdown the network 100% correctly when u power it up.
Else it works
Solution 1)
How to bypass this. Launch evox with no network cable and the applications, which will suck if you use Relax or SMB shares.
Solution 2)
Ah yes, well you can eject the DVD Drive, and your xbox will reboot, next time you start an application even with network, it will not hangup due to evox.
Solution 3)
Switch Dashboard, i switched to Avalaunch, or simply switch to MediaXMenu, whatever you like.
_after_ you done any of the solutions, you can tell the dev's of the emu/app that their emulator actually did hang, and not evox your machine. So it's the applications fault/bug and not evox's anymore.
Now this solves it, and some mod should make a pinned thread about this so we won't get those "my machine hangs up" crap anymore
