UPDATE3:  I have solved the problem.  I went into Mame32fx and changed it from Direct3d to Directdraw.  While I can't see the lettering on the inserted screens (like ok to play or video emulation isn't perfect or screens brought up by tab) perfectly, I can see it and the games all work now!!!  This is awesome.  Thank you to everybody for their help.

Basically your video card is not good at D3D.  So yes, directDraw is your quick answer.

Is there any real, visible drawback to using directdraw instead of D3D???

Aaron Giles has a detailed blog of the differences.  A simular version is included in mame/docs/newvideo.txt.

But the short is d3d is better at overlays, bezels, and effects.  DD is better for older cards.  DD + no stretch is better for original resolutions.

Any recommendations on a system's specs to run games?  Right now my brother has a P3, 1.0 Ghz processor with 256 MB of RAM.  Can he just add more ram or a nicer, newer video card to get games to work??  Thanks.

-EDIT
Would moving to an older version of MAME disallow me using any new games that have been added since the older version???

I'm actually researching this part right now - from what I've read, you can never really have a fast enough PC. From your current specs you'll likely be able to play most of the older (<=80's) games. If you really want to run the most amount of games, I'd upgrade all three for the best result.

Though I'm trying to figure out if it would be better to buy myself a 3.4 Pentium D (dual core) or a slightly faster Pentium 4 for MAME usage. I don't want to cut myself out of future compatibility if MAME will benefit from dual cores.

Yea if you go back to an older version you'll lose any fixes or new games that the later versions have added, but MAME will run faster on your machine :D.
