I can't change my background to another one.
How to do you unload a background and then reload a new one.

Re: I can't change my background to another one.
You don't "unload" a background, you just change it.
You need two things for a background: tile data and map data. The tile data are the individual tiles for the background, and the map data is where they go in the background. Once you've figured out that, (in C) you do this:
Code:
set_bkg_tiles(0, 0, 20, 20, your_map_data);
set_bkg_data(0x00, 0x1a, your_tile_data);With 1A being the amount of tiles in the tile data (in hexadecimal).
