I am not getting NES to work. When I select it from the menu, the screen flashes and returns to the menu. Selecting it enough times, I am able to make out the error "emulater advmess not found, ignoring it."
Does the update always write over the cfg files? I had customized the snes9x.cfg - mapping to my TankStick. When I updated to 7.8 - it overwrote my changes.
