Over one-hundred ships and they still don't like ya? The heck with 'em!

What I did was blast Xenos until the pirates turned neutral, then went to Rochester Base and blasted more Xenos (you're not only killing Xenos, you're helping to defend a pirate base). This can, however, take awhile.

If you want to do it quicker, I'd blast Xenos until the Rogues are neutral (which they should be by now), then start lane hacking. Or start a fight with Navy ships and bases... or just kill Bounty Hunters. It'll screw up your faction with those groups, true, but the Rogues will like ya faster!

How exactly do you lane hack?

You lane hack by shooting up a trade lane. When the blue bar goes to zero it don't work no more.

(kinda a spoiler) there's also a Rogue base in New York system. buffalo

I think the assignment of ships to bases in NY is screwed. The pirate light fighter isn't available at the pirate base, but the dagger is. And they don't use daggers. :/ If anything, the dagger should be at Rochester base, not Buffalo. Or maybe I'm just ticked off because it's too annoying to get friendly with them.

Reaper: $200,000,000.
Rockets: $100,000
The look on that pilot's face when you launch a full pod of screamers up his tailpipe: priceless

Actually, Rochester Base isn't the Rogue base, it's the Junker's base... the Rogues just, you know, "have an understanding".

The Dagger is an Outcast ship, and since Buffalo is an Outcast base...

Although, the Rogue fighter is available at Rochester... I wonder why the Junker ship isn't (would be kinda interesting to fly that thing).
