The maximum resolution is 240 x 160 pixels, and it can display 511 colours simultaneously, and up to 32,768 possible colors in total.
I believe this is inaccurate. I bought the Gameboy Advance involved Nintendo Power last month and I would bet money that GBA can display 512 colors at the same time in "game mode" and 32,768 colors at the same time in "cinematic mode".
In any case, I didn't see mention of the other graphics mode where it most certainly shows thousands of colors at once for short animations.
