I want to get access to the sprites for Mario Clash, but the only sprites I’ve seen online are for Mario and the Enemies. How can I extract the game files to get sprites for other parts of the game, such as the cameos or the stage?

I never looked into it but you could try using the debug version of Reality Boy.

Red Dragon can show you the contents of BGMaps in memory as well as individual worlds (layers). I think Guy Perfect’s emulator has those features as well, possibly with a better user interface.

Thanks, I’ll look into those two.
