Most emulators barely work... where did you get that? I can run just about everything from my xbox although my pc is prefered and to find roms. lol well your just not searching in the right place my man, it's VERY easy to find.
Also dashlaunch is built into xebuild. So if you just move the launch.ini you usually use into the xebuild folder by the gui not in the files. it will automatically add dashlaunch into your nand and it should work like a charm.
I used it and I load right into fsd like usual.
