MAME Star Wars graphics problem

[shrunkenmaster]

I'm running MAME 0.190 and have noticed that in Star Wars, the catwalks are being drawn behind the green trench lines - it looks awful. Has anyone else noticed this?

Any vector game played in mame on a raster monitor looks awful.

Try it on a version before 0.174 and let us know if it still happens.  They changed the way the vector graphics  were handled around then.  Major Havoc doesn't work right anymore.

Edit: Also take a screenshot of what you are talking about.  I checked footage of the actual machine and based on your description, MAME is handling it correctly.

technically it should be 'more correct' now

the problem is vector monitors don't update in the same way as raster monitors, they don't really have framerates as such, they just draw sequences of lines over and over, with the intensity etc. coming from how recently a line was drawn.

modern MAME versions will blend the lines that get drawn based on various factors in an attempt to simulate this varying intensity, which results in them looking more transparent, and produces the effect you're not really liking.

that's the dumbed down explanation anyway.

you might get something closer to what you want by using turning on hlsl and then turning down the 'phosphor persistence' from the overly intense default (the vector HLSL is currently just built on top of the regular one, so excuse the naming)

but as others have said, you're really not going to get a proper vector look on a raster monitor, it's always going to be a somewhat subjective field - the look a lot of people *want* simply isn't how the games looked at all.

Here is a good example of just how painfully lacking lcd is compared to a real vector.

But at home in the dark it plays just fine by my standards....without the pain of keeping a real vector working.

Where Tempest plays well in Mame,  my experience with .106 was that Star Wars played terribly....with a real yoke and ramcontrols interface.

Rolled back to MAME 0.172, problem solved! Thanks to all that chimed in
