This list appears to be a list of names for the areas. Not sure if it's connected to the overworld map, travel map, or something else. But it seems to be the only place where all the town/route names are stored in a single list.
The battle scripting commands are each an assembly routine that specifies what a specific battle script command does. Right now these are just raw pointers, but I have a feeling I'm going to want these in the future...
Each game handles the pickup tables a little differently. R/S/FR/LG store an item and the odds of getting that item (cumulative). Emerald instead stores two tables, one for common items and one for rare items. What values are used from within those tables are based on the pokemon's level.
I was considering making a feature that allowed for custom-width bit arrays. But right now this is the only data that would use it, so let's take a shortcut for now.
The tables refer to pokemon by their nationaldex number, not by their pokemon ID. So I needed a way to use an index-enum. That's the new test in NestedTableTests. That's also the reason for the change in StartCellEdit, ModelCacheScope, and IDataModel.
The new test in AutoSearchTests proves that the 4 new tables work correctly. That's also the reason for the change in StartScreen and tableReference.
'Habitat' is a pokedex feature in FireRed / LeafGreen. It involves having pokemon viewable based on where they can be caught, organized into pages, instead of just in dex order. The format is rather nested, but the table tool still works fine.
Other things should probably be in this reference file too, such as the headers, streams, and default lists. But this is a good start and should make it more expandable in the future.
