Compression Part 2

Graphics compression is working now. At least in a way so that the game doesn't crash anymore. To achieve this I maually limit the size of the compressed tileset data so that it doesn't exceed it's original size and overwrites other data.
To demonstrate it I painted the fisherman's sweater from green to blue:

Here is the result in the game:

The compression routine still needs to be improved since there are still some graphic issues within the Enix Logo and the title screen.
It will be necessaey to deal with the changing size of the compressed graphics as they are edited. I still need to figure out how to handle it that no game data is overwritten.
In the coming days I will upload the first version of the editor so you can play with it a little.
