Space Invaders backdrop resolution (mame2003-plus)

Another option would be to use a transparent RA-overlay and that would also work with FBNeo.
Drawbacks are mentioned in my asteroids/mame-backdrops/RA-overlays post(s), but there you are on a easy-peasy route to define the viewport and overlay it with a bezel or whatsoever. Otherwise, keep in mind that an within RA overlay definition the viewport part ain't mandatory (?AFAIK?) and you may have a fullscreen mame backdrop with a centered gamefield area together with an libretro/RA overlay on top of it (Mame screen covered by the RA overlay and not squeezed into a ViewPort area of it) though I am not sure on that one right now, but for me it is to late to check this one out.
But, at least for me, substituting backdrops with semi-transparent overlays, is much further apart from being the real McCoy then it is with mame backdrops. ... sigh.

This is exactly what I'm using. Using an older "bezel" .png from @Orionsangel. Here's a link to his video w/download link in the YouTube description:

Used the PNG as a RA overlay for the background and the bezel/cabinet art. For my implementation, I zoomed in and set Overlay Opacity to 0.30 (30%) so the sprite visuals appear brighter than the machine/overlay itself. Can easily brighten to taste...

I'm also using lr-mame, which has a color overlay built-in -- so the greens and reds are vibrant. I think this works well.

FWIW: For Space Invaders Deluxe (or "Part II") I also used a modified .lay file -- only including the really nice rainbow/color gradient overlay that the arcade supports. The background/cabinet art are rendered with RA. Same basic technique, but since the sprites themselves needed color -- the .lay file was required + a more modern MAME.

Images above are from my Raspberry Pi 4B, but I'm fairly certain that a 3B+ can handle.

The RA .png backgrounds w/bezel/cabinet art are in HD resolution (1920x1080) so I wager if you only want the backgrounds and not the cabinet art, just ensure that they're at the same resolution and they should work fine, without pixelation and without influence from the shader.

Please report back and say that you either downloaded it, or aren't interested in it. I just created a (temporary) directory for it in a forked repo and want to remove it from there ~~again~~ asap (don't want that one to be included by my next pull request) ;>

Done, thanks.

I don't know how much more time I'll spend on this, as I've been already been at it longer than I wanted to. Also, I'd rather play Return of the Invaders or Super Space Invaders 91. :)

Been thinking about this a well, but I'm kind of done tinkering with it by now.

@roslof That looks awesome. I'm glad I could help and be part of it.
