Yeah this is happening to me also- I only got my f200 today and have been trying to sort it out for 7 hours.
I am trying to run the mega drive emulator- as it was one of the ones listed to work.
Everytime I try to open Sonic it goes black and hums.
I am a complete n00b to this, but I believe I have done everything correctly.
Have I got the correct rom? its a zip file and I think its in the correct directory.
Would be very gratful for some help.
