I used a program called Biome painter to edit my copy. It was annoying to say the least until i found out where the start point was. I added a forest, desert, river, and mushroom biome in small strips around the start point. Hopefully this will give Plasmarf some idea of how he wants to do it later or if i have some time and his permission i could edit one and post it on here obviously making it a little less crappy than my copy.
