Here are the corresponding names of the Random Maps for AOE-ROR (it turned out they are in their in-game order, but I checked them all anyway):
0 - Unknown 4 = Small Islands
1 - Unknown 0 = Large Islands
2 - Unknown 6 = Coastal
3 - Unknown 5 = Inland
4 - Unknown 7 = Highland
5 - Unknown 8 = Continental
6 - Unknown 2 = Mediterranean
7 - Unknown 3 = Hill Country
8 - Unknown 1 = Narrows
9 - Unknown 9 = unused/unavailable - Rivers: the map itself consists of very narrow rivers, dividing the players, with no shallows whatsoever. Not very playable (water is too narrow to navigate with ships and lacks shallows).
I tried to add a map, but it won't show in the list. Could be investigated further (I didn't try very much).
The names of the maps seem to be determined by the order of the data. For example: placing a new map above Small Islands, will change the order of all maps to -1: you select Small Islands, but get the new map, select Large Islands - you get Small, etc.
BTW: could you add UP & DOWN buttons in all boxes? It would be usefull and less confusing to be able to reorder things.
EDIT: I run into a some crashes: when I try to use some of the buttons (Copy/Delete, etc.) in Units -> Commands, AGE (v3.3) crashes. I tried with auto copy disabled and all civs deselected, but no difference. [This message has been edited by aoe_scout (edited 03-03-2013 @ 01:24 PM).]
