Map size and seamless scrolling.

[Rian]

I'm fairly certain that the scrolling tut you're talking about will work with any map size, so long as it's the same size as the picScreen.

To change the map size though, you'll want to edit the MAX_MAPX and MAX_MAPY in modTypes

[edit]
Any map size, but be sure to accommodate them so that your player can be centered
