Mode 7 VRAM Map: Difference between revisions

Latest revision as of 16:01, 19 August 2024

In Mode 7, the PPU expects the first 25% (16K) of VRAM to be filled with the tilemap and tile data. This region cannot be moved around.^[1] The tilemap is stored in the low bytes of each 16-bit word, and the tileset is stored in the high bytes. Appendix A-11 has a bit-breakdown diagram of what a word of this chunk of VRAM should look like.^[2]
