MK Graphic Bug Is it core or ROM?

[Mackarole]

Hello I am playing Mortal Kombat (World) ROM on the Genesis GX Plus core & I noticed in some stages some pixels which look off & I have no way of telling if it’s the rom or if it’s the core. I haven’t tried it yet in other cores to compare but I wanted to show these incase anyone epse who played may have noticed these as well.

I noticed it on android first then saw it again on desktop.

I also noticed in Palace the background is off on the edges.

Aside from trying it in other cores what else can I do to check?

These all look normal to me. Indeed, trying the game in another core is a good way to check that.

I think this is normal. As a reference screenshot, I looked at GameFAQs and MobyGames (Arcade) . Both show the same stripes. Not sure if they did the screenshots with an emulator. I checked this in PicoDrive core (with Shaders enabled) and it looks the same:

I just took a screenshot and the stripes are there with the Genesis Plus GX core too:

And I just launched the arcade game and the stripes are actually part of the stone arch’s design.

Even the hall with our heroes in statues? I thougjt it was a bug. Doesn’t it look weird & what about shang tsungs palace how the background has the black edge on the side?

The backgrounds are correct; you can always test them on another core, in an emulator, or check out a spriters page.

This happens because the backgrounds are taken from the arcade version and scaled down to fit the Genesis resolution, and some pixels get lost in the process. The same goes for the SNES and the other consoles.
