We need your help, Starfox!

Everytime I try to convert this image into a bitmap Tool.exe gives me an alpha channel error .-.

No not the Starfox image ... this one.

The exact error message is:
==> !!WARNING!! bitmap with greater than 1-bit alpha being compressed as DXT1 <==
bitmap created: #512x#256, compressed with color-key transparency, 85K-bytes

So the problem seems that tool tries to save the image as "compressed with color-key transparency" but what I need is "true-color with alpha".
Because the DXT1 compression only allows 1-bit alpha channels but my image has an 8-bit alpha channel. So no compression no problem. At least that is how I understand it :S

Could someone please beat up their Tool.exe until it spits out a bloody bitmap file, thanks a lot

Edit: Well now that I wrote down what I need to do I actually figured it out, you can simply use guerilla to change the transparency. XD

Any tips on how to make the sun look a little bit more real?

You should try making the rest of the sky orange-ish.

You can fix this issue by going to the bitmap tag you created and setting the format to something that has an alpha, like interpolated alpha.
