Guys,
Anyone know how to switch from mode 4 to mode 0, then back to mode 4 or any other bitmap modes & back again to mode 0 safely?
every time i try it, the screen goes white. :S
Any code would be greatly appreciated.
thanks.

White and stays white, or just white for a few frames or even just 1 frame?
You do realise that when you're in mode 4 (or 3,5) that you're probably using all of the vram (especially if using both buffers) so when you swap to mode 0 you've got to copy in a map and tile data?
Actually swapping modes won't break anything, just make sure you're pointing at the gfx properly (map and tiles) and you should be fine.

I read somewhere that changing tile_mode <-> bitmap mode in the middle of screen will cause GBA hw to render about 3 blank lines, but I can't confirm it.
As long, as you wish to switch modes after the screen is rendered, you can do it anytime, there's no limitation.
