How should I edit .nsbmd textures so that I'll get it to work properly?

I don't know why, even though I do nothing with the textures, just view them, click save all then close, they get modified as if I've edited them. A good example is the cannon, which get white pixels around, although I don't do anything with the palette/texture.

Any suggestions/tips are very appreciate. Thanks.

I would suggest editing the exported cannon texture and them importing it back, leaving the transparent slots as they are.

Also have you tested the game on a real DS?
I think I saw too white pixels on the cannon even if I didn't edit them, but on the DS they show fine, so it might be the emulator.

I've found a way to do it!
The trick to edit the texture is to save only the one you've edited, if you save all, it'll cause a problem like mine.
That's a point there, if you do this trick, you'll get a good result.
Therefore I can get it done, seen here.

Well I always saved the one I edited, I never used the save all button (and I dunno where it is... )

But good that you found the problem and a fix

Really? So this's the point.
Also, the save all button is below palette selector, near export the bitmap. ^^
