The Neo Geo X has been jailbroken now and will allow other emu's to be used.

This is really cool.
A bit pointless, why would anyone bother doing this, as for most people with a Neo-geo x have or will probably already have a open source handheld to begin with? Rendering this hack an unnecessary expense or effort, but people love their hacks, but isn't it very strange this jailbreak appears shortly after the falling out and disbandment with that manufacturer who was making them for SNK? Hhmmmm.
Well, I guess it has been done just because it could be. So, the point was just doing it I would guess. Yes, chances are most owners of the system already have a way to play games for other systems on another handheld but someone must have wanted to do this.
I'm actually surprised it took them this long. I won't be doing this to mine but still cool that it can be done.
