ok, I need to bump this back up the list.

Every night I keep

and need some other peoples input on this.
I see the computer's boot up sequence on the TV, I see the MAME logo screen, and I see the MAME MPG that runs, and then I even see the ArcadeOS menu program running with the 3 default games. I can move around and see the different screenshots, etc. My problem is when I attempt to run one of those games. I press "1" on my keyboard and it says "running
gamename". After about 10-15sec I think.... than the screen goes black. I get nothing. I am assuming that the game is running in the background, but I don't see anything on the TV any longer.
When I initially start the ArcadeOS bootcd installtion, I did choose that I am running a VGA card with output to TV & TV....... in fact I've gone through the installation 6 times. 4 times was to choose a different monitor setting, the other 2 times were to try a different version of dmame (v100 and then v79)
I've attempted to run ADVMAME, but when I run the ADVCFG program at the very last part is says it can not run the configuration screen and boots me back to the DOS prompt.
Kinda lost at this point. Is there a setting I can go and change? Should I go and change my video card ROM again, so that it outputs lower than 60Hz if possible?
And yes, initially I had to modify the video card Rom and reflash it because the video-out port, on default, was booting with PAL settings, and I require NTSC. But I do remember that by default it outputs 60Hz... I may be able to go back in and lower it. Would that help, or could I wreck my TV?
