This is looking fabulous!!!

The new vector setting is highly engaging and of course also works in FBNeo and MAME current.

(Major Havoc being a brand new merger of two Progetto Artworks)

I also experiment with this setting for the old backdrop games, however with less radical effects and by applying scanlines.

(oops, backdrop being broader than bezel artwork here…)

Again a lot of inspiration, many thanks!

When it comes to Vector Games, cores behaves differently, so to keep thing simpler and stay with the core defaults, I’d say to use HiresGames_fast presets for MAME2003+ and Normal for FBNeo.

  • Mame2003+: 1024x768 output resolution -> HiresGames_Fast presets (1x upscale ) -> 1024x768.
  • FBNeo: 640x480 output resolution (not configurable) -> Normal Presets (2x Upscale) -> 1280x960.

That way the presets should look similar and as intended.

The background image is upside down, how can I set it to be right side up?

Quickest fix is to switch Video driver between GLCore and Vulkan

With “Normal Preset” you mean the Presets-VectorGFX directory in root of the repo?

Yes, that.

This is now interesting: In my tired eye, MAME2003+ is best, then FBNeo, then MAME2003 and MAME current being worst by far:

MAME2003+:

FBNeo:

MAME2003:

MAME(current):

(with MAME(current) I tested both presets and the root directory preset seems a bit better)

Your view?

Perhaps it’s just a matter of different settings, for example input or output resolutions? Could be something simple to normalize the 4.

Yes, 2003+ outputs at 1024x768 so has less aliasing, where FBNeo just 640x480; They both looks ok if not zoomed in IMHO. (and for a fair comparison, the screenshots should be 1:1, but they all seem to have a different resolution (?) )

I cannot speak for other cores, as I don’t know how they render the beams; what appears evident is that the bloom is not doing its job in Mame 2003 and Mame current; that could be indeed due to an higher core resolution or a less bright picture.; That could be probably worked out by pushing the the input signal gain and/or tweaking the blur radius by a small amount.

Thank you! Sorry for the unclarity on the shots: Identical settings and identical slangp presets, only the 2003 cores having the hires presets. Screenshots then just cut out manually in order to save space.

Its identical settings. Just switched the Core Association. MAME current looks bad in both presets.

It is like its output resolution for Vector games is really low.

Exactly, also the fonts pixelate.
