Last night I was trying to play tempest, asteroids and so on but none of the games worked. All I had was a black screen. I do believe I have all the roms hence I d/l the full rom set. I played with the mame32 default settings under the vector tab. Nothing worked. I changed the resolution of the monitor from 32bit to 16bit and 800x600. Nothing I tried worked.
I have a P4 2.4 with 512ram and an ATI Radeon Video card.
