OK so... I think I've found an somewhat hacky way to do this. I made a QuickBMS script that manages to successfully extract all the images (as raw files) with their palettes, but if you wait I should be able to make a program tomorrow that just extracts and converts them into PNG.
This method finds 551 different files, but I'm not sure if this is the only format. If you find any different formats (i.e. images that show up with different settings in TiledGGD) then please point out those as well.
