IIRC, this is rubbish. Because you couldn't galactic hyperspace into Oresrati.
Anyone able to corroborate?
Correct, there is some discussion of how the galactic hyperdrive works in the different versions
Well, according to that wiki article linked by Dr Beeb, on some versions of Elite, you could indeed galactic hyperspace into Oresrati.
The BBC Micro had fixed galaxy entry-points, but other systems didn't necessarily obey the same rule. From the wiki:
In a text-only trading version of Elite coded by Ian Bell in C around 1999 the planet number is conserved across a galactic hyperdrive jump. These are listed in the planet list but are not visible to the player. This choice gives the appearance of random, but predictable, entry points (determined by your departure planet). This choice allows access to the large isolated island of systems in Galaxy 7 and is responsible for the the ancient warning "If you leave Galaxy 7 from Rainza you will end up at Oresrati in Galaxy 8".
This choice was implemented in some post-classic versions of Elite, including ArcElite.
So in ArcElite and some other (un-named) versions of the game, it was indeed possible to gal-jump into Oresrati. Just as you can in Oolite.
