FPS keeps dropping when I replace colors?

[N64Mario]

Can anyone tell me why my FPS keeps dropping when I replace the colors this way? And/or if there is a way to fix the FPS from dropping?

Pressing the fire 2 button gives him the charged shot color swapper thing.

I'm trying to make a color replace code that fixes my character, so his colors don't get mixed up and eventually gain 1 solid color for all values.

Replacing a color does so, for every frame of every direction of all animations... and so is obviously a slow command.

Using HWA it is possible to do similar things (however much faster).

What is HWA anyway? I read that it is still beta, and there are some things that don't work.

Anyway, I think I can work around this by exaggerating a few palette RGB values. Although this won't make the characters palette accurate to the original games.

I think MMF2's color replace code has an obscure bug/glitch that once a color is replaced, it is replaced permanently. Therefore if a same color gets rotated around, it will eventually lead to a solid color. I wonder if they will ever try to fix this.

It's intentionally like that.

If you want something more flexible, you could try a pixel shader doing the replacing.

So why can't there be a code that changes a color of the current 256 palette set given? That way, if a sprite is using a specific index color of the palette provided, it would only affect that area, and not all color areas. In other words, the current palette at the start could be overwritten with another user palette provided.

It's a good idea, but very few people use 256-colour mode any more, because it doesn't work well with multiple applications running at once.
