Using the mod "Armoa's Core 1997's Dimensional World" How do i change the mining world "y" height?

Ok, so first you need go to the config folder in your .minecraft. Then, once in the folder, go to aroma1997's folder. Then, go to Aroma1997sDimension.cfg, open this using some kind of text editor. Scroll down to where it says I:worldHeight=80, just change the number to 256. If you want to change the ore density, go to where it says I:oreDensity=1 and chang ethe number to 5 or lower.
