Ok I'm a bit of a newbie to GameEx, and I'm having problems getting any of the emulators to launch. I've gone through the install and evertything within the front end appears to work fine. However when I choose a game it seems to go to a black screen for a few seconds then return to the gameex front end. The emulators will work fine if I start them outside of GameEx. I've gone over and over the settings and have not found anything that will work. Any help would be very much appreciated. I've tried Mame32,NesTopia,Project64, and ZNES all with similiar results. My system specs are as follows: Vista Ulitmate 32 AMDX2 5200 2 gb ram 7900GS graphics card.
