[Request] add retroarch antiflicker shader

[QcSamuel]

retroarch has a antiflicker shader in the misc directory this would be useful for neogeo games to stop the shadows flickering

[LiuSky]

Can you mention a pr? @QcSamuel

[QcSamuel]

@LiuSky there no pr ? just asking if this shader could be added to the app https://github.com/libretro/slang-shaders/blob/master/misc/anti-flicker.slangp

[LiuSky]

Does the mame4ios shader flicker? Is there a demo or video to see the scene @QcSamuel

[LiuSky]

There will be no flash shrink on my side. Could you please provide me with the rom package? @QcSamuel

[QcSamuel]

@LiuSky try samsho4.zip (Samurai shodown iv)

[LiuSky]

I gave it a try. It looks like the rom package itself is like this. Or are you in libretro That didn't happen @QcSamuel

[QcSamuel]

the game is like this but if you apply the libretro antiflicker shader this stop the game flickering this is why i want it added to mame4ios

[LiuSky]

That's great. It seems that only the shadow of a person can do what you say @QcSamuel

[QcSamuel]

there also the health bar in samurai showdown

[LiuSky]

This should be a core underlying MAME issue. @QcSamuel

[QcSamuel]

its not the flickering is also on hardware neogeo https://wiki.neogeodev.org/index.php?title=Transparency_effects
