Game Boy Advance Dev: Drawing Pixels

Game Boy Advance developers can draw pixels using three increasingly complex methods. The simplest approach uses bitmap mode 3, which converts the entire 240x160 screen into a direct-color surface where each pixel is individually addressable, making it ideal for games like Doom but limiting developers to just one background layer. Drawing on sprites requires working with tiles and palettes, where pixel data gets compressed with two pixels per byte and must be written in two-byte chunks, creating memory management challenges but allowing for variable-width fonts and detailed graphics. The most challenging method involves drawing on tiled backgrounds, which combines tile manipulation with tile mapping but provides access to all four background layers, essential for games needing both custom drawing and traditional background elements.
