The following byte is only used with custom sprite: for Extra byte 6: Timer of multiple coins (0 means only one coin) obviously used when it spawns coins. I believe enabling 'Disable cape killing' bit in configuration should fix this. If I hit the sprite with the cape from slightly above, sometimes that causes used block to generate 1 tile above where the sprite was. When hit from below or the sides, they briefly spin around, allowing Mario or other characters to pass through them.

Rotating Blocks, 1 also known as Spinning Blocks, 2 Turn Blocks, 3 or simply Blocks, are yellow blocks with eyes that first appear in Super Mario World. Tested With:-Lunar Magic 3.31-PIXI 1.32-bsnes v115-SA-1 1.40 The biggest issue this sprite has is setups provided with SpikeSpriteBlock.json don't work correctly, you confused timer with sprite state which means sprites won't visibly come out of the block, and will have sprite state 3E, which thankfully doesn't crash the game, but makes these unusable.

The content can be filled in various ways. It's non-dynamic so it can only turn in four directions but it is easier to insert and more than four can be on-screen as well. This is a spiked question mark block, a block which rotates itself while one side is spiked. New Super Mario Bros - Spiked Question Mark Block (non-dynamic)
