Mame over-stretching a couple of classic games
Sylentwulf:
27" TV set at 640*480 res. through S-video to a Radeon 7200.
Mame stretches out missile command and pac man too much, missile command scrolls the screen about an inch when I go to the top/bottom/sides.
Pacman just cuts the bottom 1-2 inches off.
Using Mamewah.
Thanx!

My guess is that MAME is trying to display the games at something other than 640x480, and your video card is having trouble pushing other resolutions out to the TV.
The simplest solution is to disable "switchres." In MAME32, do the following:
Go to: Options->Default Game Options
Click on the Advanced tab.
Uncheck the box that says "Switch resolutions to fit."
If you are using a commandline MAME, then set the following line in the mame.ini file:
switchres 0
(the default is "switchres 1").
Or if you are setting your mame options by using the command line, use the following switch:
-noswitchres

EDIT:
I am assuming that you can see your entire desktop when you are not in MAME. If not, then you need to experiment and see if you can get your video card to output any other resolutions (such as 800x600) that fit in more of the desktop.
Sylentwulf:
I'll give the switchres 0 a try in the mame.ini
But, doesn't that mean it won't be changing any games at ALL? Most games it stretches perfectly, the desktop and mamewah look good.
Maybe I'll give 800*600 a try, the only reason I had it at 640*480 was because windows was hard to read and it seemed to flicker a little bit less.
Just found out that Tapper also gets overstretched last night.

Odds are your video card can only output correctly to the TV at 2 or 3 resolutions -- probably 640x480, 800x600, and (maybe) 1024x768. When trying to find a good resolution, Mame tries some other oddball ones, like 400x300 (or much lower if you are using DOS mame, but I am assuming you aren't) and these don't display right because the video card wasn't designed to handle them (not for TV out, anyway). However, if you are using hardware stretching, it doesn't really matter much what resolution you use, the games will come out about the same (with some exceptions -- vector games look better at higher resolutions, for example).
Mame does a series of calculations to decide what resolution to use. Odds are that for the games that are fitting correctly, it is using 640x480, so setting it to use that for ALL games probably won't be a problem. If it is, then just use the switch on a game-by-game basis (I haven't used MameWAH, but I'm sure it lets you set this).

I first noticed this with Tapper, I have an ArcadeVGA with an arcade monitor, I'm just waiting for MinWah to check out the bug with the ArcadeVGA M.A.M.E. Res. Tool and Mame .85 to correct mine, Hopefully!!
