Multiple Questions.

GalacticaCraft
Well here I'm asking what you think about the GalacticaCraft mod and where I can get the newest
versions since I've tested this and I really liked this mod.
I've tested this mod 2 days ago when I downloaded it from here.
And I don't know where to get the original version.(Been to lazy to google for it :rolleyes:/>)

Pheripheral
Well here I'm mainly asking how to make

a peripheral since I don't know how to make one..
I'm currently learning Java(again) and wondering if
there is a helpful tutorial somewhere about how to make
a peripheral.

I like galacticraft. It looks fun, and it's well done. On making peripherals, there's no real tutorials, and I've never tried it, but I believe the peripheral interface it is available in Peripheral Help and Discussion. Learn how to use Forge, then download the interface for peripherals.
