Well, sorry I need a patch for my secret level in my Mario mod.
It'd be Level 17, so LEVEL17.CK1, together it's 16 levels(4 warp zone with 4 level) + 1 secret level(LEVEL17.CK1)
Use the 32 levels patch (it's in the Marooned on Mars section) and then make a LEVEL17.CK1 file and place a 17 sprite on the world map. It's easy. (I may be wrong - I've never used that patch.)
