This controls the sprites in the game.

Format

This example uses the sprite data for Ninten forwards, located at 2ABAC-2ABBB:

10 20 10 02 18 20 10 03 10 28 11 10 18 28 11 11

Sprite are made up of 4 PPU tiles, each of which are four bytes in the sprite data, in order:

  1. Top-right
  2. Top-left
  3. Bottom-right
  4. Bottom-left

In this example, 10 20 10 02 is the top-right part of Ninten.

Tiles

Each tile's sprite data has its location, palette and PPU tile. The position controls where the sprite is drawn on screen relative to the sprite's position. For example, changing the location on NPCs causes parts of their sprite to be detached from the rest.

  • Byte 0: X location
  • Byte 1: Y location
  • Byte 2: attributes
    • Bits 0-5: **Unknown**
    • Bit 6: mirror X
    • Bit 7: mirror Y
  • Byte 3: PPU tile index
    Selects the tile index of the sprite gfx (58010 to 5E80F)
