| It's possible to copy 1.6.1 files over, as an "astronomy" update: 
 At the very least in directory 'data':
 extrasolar.ssc
 extrasolar.stc
 starnames.dat
 numberedmoons.ssc

| "what do you mean with "non minigl?" version?" I mean something like a "2D" version. For those who are using graphics cards such as CyberVision PPC.

| @afxgroup I went to the official website and have had a look at some screenshots. This piece of software is damn amazing!
 What are the minimum hardware requirements for the OS4 port?
 Would a non-MiniGL port make sense or it would be too slow to be usable?
