Yes, all the maps were on the original disc, and before editing, they opened and played without any problems.
By the way, regarding the maps – I downloaded a bunch of games from some Heroes website, intending to experiment with them, but the archive somehow downloaded as corrupted.
So, the maps have the original rules, definitely.
I checked the map, here is the list of errors:
Object and craig intersection: 160:76, ground floor.
Object and craig intersection: 160:77, ground floor.
Object and craig intersection: 160:79, ground floor.
Object and craig intersection: 160:78, ground floor.
Object and craig intersection: 20:107, ground floor.
Object and craig intersection: 126:151, ground floor.
Object and craig intersection: 19:187, ground floor.
But the rules are quite simple...
