I didn't dominate the Rock in a shuttle, I destroyed it. There's a difference. I also destroyed the Voinian Dreadnought in a shuttle that was stock except for a Plasma Siphon.
And the Emalgha don't have any proprietary technology. Anyone who can land on Emalghia can buy their cannons, ships, and freighter upgrade.
One trick to being able to land on almost any planet is to accept one of the bounty hunting missions from human independent space. This makes renegade kraits and helians, flagged with infinite auxiliariness, attack you wherever you go. So if you go somewhere within two jumps of a place that you can't land, destroy the renegades, and either land or jump, and keep destroying the renegades, eventually your legal status will rise enough that you'll be able to land.
This does not, of course, work for the human renegade worlds. Luckily, however, I believe that accepting north tip bounty hunting missions and killing the resulting crescent fighters near Pariah, Yelts, or Riomar accomplishes the same objective.
And remember: being hated on Iothe Prime doesn't cost, it pays by letting you become a Captain of Freeport and attack Histiri Station.
