if i use 256-colours for the images in a GBA game, can i use more than 256 as long as they are not on-screen at the same time?? i dont know if this is possible or if you has to load a new pallete or something, and what affect this has on the rest of the game and if it would compromise other features, or not?

Yep that's definately possible. Loading a palette at any time is absolutely fine.

You can rewrite the palette during vblank. In fact, you can rewrite part of the palette during draw time if you want separate palettes for the playfield and the status bar. The StarTropics games for NES do this; it's even easier on the GBA with all the memory dual-ported.

sounds good and will allow for extra flexability and creativity without making images higher colour depth and take more space. thanx for the info

A-ha! I bet that's why the colors on StarTropics were screwed up on the earlier NES emulators. (Good game, BTW)

So I guess that if I build my sprites with individual 16-colour palettes, I can change the palettes in different 'rooms' and reuse the same sprites? Interesting idea....

Of course you could also do the same thing within a room. You could have a couple of different 16 colour palettes loaded at a time and have sprites using the same pixel data but a different palette.
