All textures in the post-1.80 models look similar. The reason is that the emission map is embedded in the png's alpha channel. You will need an image processing program capable of separating a texture's individual channels in order to view it porperly.
I see, thanks!
It's hidden away in Photoshop - selecting the "Channels" window shows the RGB channels AFTER the transparency has been applied, we want it BEFORE.
To do this:
Select the layer, then go to Layer menu -> Layer Mask -> From Transparency.
The alpha channel is extracted into a greyscale mask attached to the diffuse layer, which is now an opaque RGB layer.
To see the opaque layer on its own - disable the mask layer.
To see the mask as an "Emission" layer, holding left Alt key, and clicking the greyscale alpha mask layer that is linked to the diffuse layer will show only the alpha channel - the emissive parts in white.
