Nintendo Puzzle Collection palettes

[Ploaj]

So I'm trying to rip/modify some sprites from Nintendo Puzzle Collection and I'm having some issues figuring out the graphics.

Some of them work out fine.


Other do this thing.
It's the right palette, and you can sort of seesome right colors, but it's really messed up.

Is there any kind of compression it could probably have or something? I took a look at it in hex, but it has no header at all so I don't even know how to figure it out.

Here the file I'm looking at.

The graphic is at 0xAFC8
The palette for it is at 0x4C0

Any help would be appreciated.
