Description

Mode 3 provides one 256-color background, allowing photographic-quality images on the SNES. The tileset exceeds 32KB, requiring split DMA loading with explicit bank bytes via an assembly loader.

Architecture

• Mode 3: One BG, 8bpp (256 colors)
• BG1: Full 256-color image
• Tileset split: first 32KB + remaining ~7KB in separate DMA transfers
• Assembly DMA loader handles bank byte for SUPERFREE sections in bank $01+
