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.

  • Byte 0: X location
  • Byte 1: Y location
  • Byte 2: attributes
    • Bits 0-1: palette
    • Bits 2-4: unused
    • Bit 5: priority (0=in front of background, 1=behind background)
    • Bit 6: mirror X
    • Bit 7: mirror Y
  • Byte 3: PPU tile index
    Selects the tile index of the sprite gfx (58010 to 5E80F)
