I've got a problem:

Every program, what I used, thinks, that the 2(jazz blue and similiar to jazz blue) colours are the same.
So... My question is, what can I do now?

Well, for a start, what program are you using?

Graphics Gale free edition, paint and photoshop

Ah, well as far as Graphics Gale is concerned, I can help you. Do you have multiple colours in your palette that are the same?

I have 16 black colour.(I mean 0 red,0 green,0 blue)

That doesn't matter. Try using Gimp, it doesn't meddle with palettes.

I'm pretty sure Gimp doesn't use standard palette formats, and that it doesn't allow multiple palette entries of the same colour. Or at least it was something like that, I sort of gave up on it. Mind you, if you get it to work, then you've done better than I have.
Also, I can look at the files for you if you like. Just send them to me and I'll see if I can fix the problem.

I have used Gimp succesfully with same colours in the palette without palette losses.

In that case, I must be getting mixed up. I haven't used Gimp much.

You probably should stop using atleast paint, it probably makes the palette compressed so you lose the colours...

I've sent an email to you.

Okay, thanks, I see the problem properly now, and it's actually pretty simple. The tileset extractor swaps the first two palette entries (it gets annoying sometimes), so all you have to do is swap them back. In Graphics Gale, just hold shift and click-and-drag one to the other. Then it should work perfectly.

It doesn't working. Or just I'm doing something wrong.
It's working now.
Thanks for help

I'm back with an other question...

The upper one is the mask in JCS, and the downer one is the normal. What could be the problem?

I think the problem is the exact same one as the first image. Try swapping the first two colours, and see if it helps.

Now I think it's other...
