"Dirty pixels" in MAME
05/25/20 10:41 PM


So I was playing a good old game of Double Dragon in MAME and decided to take a screenshot. When I looked closer at it, I noticed the pixels were not only stretched (due to the default resolution) but also had strange artifacting.

Here is an example

Zoomed in to avoid eye strain.

Now I got to wondering what was causing this, and I thought it might just be because of the stretching. So I set MAME to start windowed, turned off 'unevenstretch', and set the window size to be the exact size of this particular title, 256x240. To my dismay, this only made things worse:

Pixel perfect?

The artifacting is still there, but now the discolored pixels are the same size as the proper ones, making everything look blurry and muddied. This definitely isn't what the game is supposed to look like, here is the same section of the stage taken from a sprite ripping site:

Looks a lot cleaner.

So what am I doing wrong here? I'm no expert at using MAME, but there's gotta be a way to fix this, right?
