How to change compatibility?

[boiled_vodka]

There's a map I want to add CP.

I can play it in 1.24b patch but I can't add cp into it.

Also tried to deprotect it with an utility, but I only see terrains but no obj & triggers of the map.

If there's any easy(ier) way to change compatibility of the map, Can sum1 make a post of it please.

Tut with images will be helped alot!
