Changing ratios :

If you want to modify the ratios of the mod to give your game numbers you prefer, here's a simple method for those who didn't want to look at the files. It is in fact easy to do it.

My mod adds 2 files in the "Config" folder. One about the gamestages, and the other is the spawing occuring in the wilds. You can take the one from the multiplier you want and take the other from another multiplier.
Example : You want the x8 hordes but only a x4 wild spawns. All you have to do is download one of my mod, then empty the "Config" folder. Then you take the gamestage.xml file from the x8 version, and place this file in this folder, and take the spawning.xml from a x4 version to place in the same "Config" folder.
You can do that for every version you want, the file will replace each other, each time you decide.

For those who already knew that it's easy, but many of you may not know.

Changing numbers or mix the biomes spawn rates :

You can also do more difficult things, like mix the biomes spawn rates if you want to. For that, thje spawning.xml have the 5 biomes marked by green comments (the <!-- --> for those who don't have XML knowledge). Below those green comments, are the actual biomes spawn rates. All you have to do is copy/paste the lines you want into the same file in your "mods" folder. Or you can change the numbers yourself if you feel comfortable with it.

Everything in my files is notified and marked, you can, even with no knowledge, understand pretty well what's going on in those. Feel free to ask if need be, I'll answer eventually. You may also send a PM if you want, sometimes I just zap all notifications without seeing anything.
