Palette not saved

[devnewton]

Hello,

I am starting a little snes homebrew project. I try to import a spritesheet. It works nicely, except for the palette.

How to reproduce:

1. Create a flf file for snes (chose snes system, tiles with 4 bpp) ;
2. Import a 128x128 spritesheet with "generate palette" checkbox on ;
3. Save the flf file;
4. Close the flf file;
5. Reopen the flf file => the palette is lost :(
