Bilinear filtering. You can disable this, but the stretching artifacts become much more noticeable...

...As you notice.

"SDLMAME" has a feature called -ues (or unevenstretch) - defaults to on, but you can set to disabled (-nounevenstretch) and then get 1:1 pixels with integer stretching. The downside to this is you will get windowboxing effects when it's not an exact integer stretch.

You can acquire a Windows binary of "SDLMAME" sometimes, or build one yourself with the usual compiling tools and official MAME source. (Technically you shouldn't call it SDLMAME any more since it became part of the actual MAME project...)

I've often wanted this as a feature in standard MAME.
