Map Palettes

The map palettes are displayed correctly now! Worked faster than I expected :)

I played around a little with the map editor and added a second floor to the house:

I also renovated the dark part of Freejia a little:

Map Editor

It's now possible to edit the maps in the editor just as I did in the following screenshot:

I still need to finish the compression routine to make it possible to write the edited map data back to the ROM.
I'm also working on the map palettes currently. A map consists of several palettes (up to 8). The palette which a single map tile uses is assigned by a 3 bit index that is part of the tileset data.
With this index I willtry to display the map with all the right palettes.

Display Map Layers

I improved the map loading algorithm to support the display of the different map layers. You can now select the layers you want to display in the editor. The following screens show the different map layers for Edward's Prison.

Map layer 1:

 Map layer 2:
