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:
- Top-right
- Top-left
- Bottom-right
- Bottom-left
In this example, 10 20 10 02 is the top-right part of Ninten.
Tiles
Each 4 bytes is [OAM]:
- 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)
