Final demo map making

[That S0nic fan]

so I'm wanting to make a map for final demo but i don't have a easy way to make the level

There isn’t an easy way to make Final Demo maps; it wasn’t easy at the time either. Download the mapmaking tools from that era and try to go from there.

This should work. Just make sure to run it in administrator.
It is also quite different from ZB, so take your time to learn as much as possible on your own before asking everything.
