I got do some jiggery pokery on certain maps where they actually used massive grhs but used main layer to force them into 32x32 tile, Engine im using hasnt got the constraints on size so it shows full size, So im going have to rework my main layer to force them into 32x32 to make the map form correctly then go round and decide if we want to use the "blocked" tile in the map files.
The thing i like the most about this rebuild, to modify any of the maps I need to use the VB6 map editor

The next thought process is manging all the map zones and best way of doing it,
