Metasprites general info request

So I'm trying to figure out what exactly meta sprites are and I can't seem to find any documentation for some reason. There's a metasprites tab on NES Screen Tool, and I was wondering if that data ends up in the .chr file or somewhere else.

I'd like to have more information on the subject in general, so if anyone happens to know where there's some documentation on the subject I'd appreciate it if you can point me in the right direction.

Thanks

The NES's hardware sprites are always 8x8 or 8x16 pixels.

"Metasprite" is just a term of art that means a single logical object (enemy, player, &c) that uses multiple hardware sprites.

So they don't equate to anything in the hardware? It's just something you have to implement programmatically?

Thanks

Exactly. Which means you have to manage it, and have some way of encoding how you combine multiple hardware sprites to make a single actor for display.
