Looks simple, but can't work out transparency. [Solved]

Hey guys,

so I've got a game here I'm trying to rip that looks super easy, but the big pieces of art seem to be giving me some grief.



As you can see, I can get them working just fine in tiledGGD, but the outline disappears with transparency enabled. When disabled, it looks like this:



As you can see, there's a bunch of weird colors going on in these spots... And I have no clue what to do to fix this. Here is the file these came from specifically:

If anyone has any clue, I'd appreciate it:

4x4 Tiled, 16 BPP, Little Endian
Palette is RGB.

Thanks!
