   the GBA stores sprite rotation HOW?

     so there's 128 sprites that start in RAM at 0x07000000, they're 6 bytes long, and the second sprite starts at 0x07000008

     yeah they're 6 bytes long but stored every 8 bytes

     the 2 bytes between each object are the sprite rotation.

     But they're not the sprite rotation for the sprite they're next to!

     instead, it takes a total of 32 bytes (4 sprites) to encode one single sprite rotation entry.

     So the first rotation group is at 0x7000006, 0x700000e, 0x7000016, 0x700001e

     so there's 32 rotation groups, but they're interleaved inside the sprites. for... reasons

     and then inside the 6 bytes that define sprites, there's a bitfield that determines which rotation group it uses.

     @jens sharing rotations makes sense
     stuffing them inbetween each sprite? less so

     @foone So several sprites can use the same rotation? Makes sense, in a way.
