I made a sprite test level to help in figuring out sprites. You can use it to test anything though.

It is in 1-1. It has 1-1-1, 1-1-2, ad 1-1-3. The pipe on the left is always the lower number area.

Hopefully this will help people to learn and build. Also, I am hoping this will encourage you guys to help me finish the sprite data.

I am using a clean USA rom.
