Also, When I alter textures using PaintShopPRo, they change to 24/16 million colors instead of 8/256 colors.
I use the "decrease color depth" for 256 colors but I get the message that it can't be done, only with 16 million.
Is there a trick that I don't know about?
Does it make a difference if it's 16 million or 256? It seems to work OK on my computer.

I don't know if it makes a difference, 256 or 16 mil, but I just checked and many if not most of my textures are 256.

Maybe you should check the options you have as settings for saving tga files. Mine are 8bit and uncompressed ... changing them from 16 mil to 256 worked fine for me in PSP
