Clockwise: Palmtree Panic, Tidal Tempest, Round 2, Wacky Workbench, Stardust Speedway, Collision Chaos and Quartz Quadrant 2, and Metallic Madness in the centre.
That's my assumption at least.
Does anyone have screenshots of the Past, Good Future, and Bad Future versions? Those might help to confirm some things. I don't have an emulated save file with D.A. Garden unlocked, and I'm currently not at home so I can't just take a photo of my TV either.
