I can't even see the bullets on my screen  :'(

Please ignore if you have already played with these basic settings:

Have you played with the vector beam width and intensity settings in mame?
With a value of about 3.00 for both, Asteroids looks (what I consider) 'acceptable' on my particular LCD.
The bullets are definitely visible and all lines clear and bright.

Specs:Mame32 v0.105
Mame32 Resolution settings set to monitor's native res/refresh,
Stretch using h/w set to monitors aspect ratio (16:10).
Full Screen Brightness: 1.00
Dell 2405FPW (DVI)

Of course this is after setting up the basics  - running in native res, digital connection, adjust settings through monitor's menu, adjust settings through display properties for vid. card - brightness, contrast, gamma, etc .

I jacked up the Gamma and Contrast with great results.   The default MAME are way too dull.  Bullets look awesome on my high end LCD but the lower end is still very acceptable.

I'm not running Mame 32, just standard Mame with Maximus Arcade frontend. Is there any way of adjusting the vector settings without Mame 32 ?

Should be in your mame.ini - look near the bottom for vector options.

To add to this - from John Hardy's mame32 pages from about 5 yrs ago regarding an LCD:
"Note: When you use an LCD and Mame32 remember to deselect the switch res and switch color depth so you can run at native desktop resolution.  No mode switching and no interpolation from lower resolutions."

These should be somewhere in the  ini as well (video options?).


Applicable to larger screens: "The increase in vertical resolution allows for better integer stretching in Mame32 too, so you can for instance run at desktop resolution and choose the scanlines options and have the image take up more room than at 1024 vertical."
And Widescreens(16:10): "It's necessary of course to set Mame32 to 16:10 otherwise you'll get a squat stretched picture.  Since most arcade games are 4:3 standard resolution, you're going to get black bars on the left and right in a letterbox style. "

You sir, are a genius. After working out how to create a mame.ini file, I found the vector option just like you said. Tried various figures and found a value of 1.5 (default was 1) boosted the brightness of vector lines and bullets beautifully!

This has been bugging me ever since I built my cabinet and it's a relief to finally have a solution. Thanks very much for your help!  ;D
