After a few years of absence from MAME and MARP, I have now re-discovered the classic games of the 80's (like I do every few years).
Having bought a new computer (AMD Athlon 64 3200+ processor) I thought it would be a good idea to upgrade my mame32 37b15 to the latest version available and I found Wolfmame.
But I can't get a good picture on my screen. It is very hazy and fuzzy. The old mame versions (mame32 37b9 and older) work fine with a very clear and sharp image. Not so for Wolfmame. Is anyone else having this problem?

Thanks

This is because of hardware stretching which is used to display correct aspect ratios. You have two options:

1. Turn off hardware stretching.

mame -nohwstretch

This will not give you correct aspect ratios though.


2. Leave hardware stretching on and use Direct3D without filtering.

mame -d3d -d3dfilter 0

This will give you a sharp picture.


These are command line parameters. Just look through the GUI and you should find the corresponding options.

On a computer monitor having a sharp image is "wrong" though. A real arcade monitor displays a smooth image.

Thanks for the solution Buttermaker. I have done what you suggested and put the scanlines at 25%. I now have a much better image, much closer to the old arcade feel.

depends on the game, but for the most part the way mame (and streching) smooths the images is WAY more blurry that old CRT's used to do it...
