I have a modded box (xecuter3/avalaunch) Since I got it, none of the emulators will start without freezing up on the first menu for whichever emu I try to play. I have to restart the box every time, no matter what. Has anyone else heard of a problem like this? I'm not sure what info to post here to help the diagnosis, but I will run through some more forums to see if I can learn anything else about it.
You should consider upgrading either the dashboard or the emulators, or both. See if this will fix the problem. -Mike
