Can someone explain to me why MUGEN hates gradients?

A 255 color, indexed sprite of a cloudy night-sky looks fine, but once you load that sprite into MUGEN it looks like a 20 color image.
Why does that happen?

What is MUGEN doing to recognize a fade differently from everything else?

Mugen's ability to draw colours is a little limited. Mentioned on elecbyte forums and i don't remember all the detail but i think it's limited to 16bit colour depth. A gradient kills that, and it's colour count is reduced by the graphics engine to display all the other stuff as well. Or something along those lines.

Unsure what happens to a gradient if it's ALL you have on screen.

They say a little knowledge is a dangerous thing, but it's not one half so bad as a lot of ignorance.

Well maybe that partly explains why afterimages are gayed up. Hmm.

think of it as the screen having a 16bits palette that can't be modified; so even if you load an image that is 2 colors, those colors won't be rendered properly if they are not in mugen's 16bit palette. Normally you can't notice such a small cahgne in colors, but in the case of gradients, it can fuck them up really bad.

I had the same problem with my pause menu

check the gradients in the inner part of the bottom and top bars. They are dark gradients but still have problems.

However I found that the problem is HIGHLY visible when you're using low gamma configuration on the screen, if you use a normal gamma (default) the problem is less noticable...

too bad I like my low gamma config
