You have to use Pirahna to beat Zico,if you have the FURY added content you can also use the new Pirahna [slightly higher stats] to beat Zico.
Here's a good tutorial on how to beat Zico.http://www.wegame.com/watch/Wipeout_...Zico_Tutorial/
It doesn't matter if you use stick or D-pad,what ever works for you.
As for changing controls from default,well it's personal preference ,the only two that make any worthwhile difference are changing air brakes from L2R2 to L1R1 and dropping the sensitivity from 100% to around 65%-70% [less % = more sensitive in wipeout],and the other is making acceleration 10% as it means you don't have to have your thumb constantly pressed down hard on the X button.
Zone trophies are all down to practice,95% of people that have got Zone Zeus have done it Anulpha Pass forward as it's the closest thing to a Nascar type oval track.
Wipeout disciple :just us different craft while attempting to get Zone trophies will get you loyalty points up the quickest,you will get quite a few points with Pirahna is you remember to end session rather than just quitting beat Zico Speed lap attempts.
By the way.
Wipeout HD/FURY has been released on Blueray Disc in Europe 16th Sept.http://www.joystiq.com/2009/09/14/wi...ray-in-europe/
No release slated for North America ..... yet again! ..... You guys get shafted big time by SCEA with a lot of Wipeout titles and have been so for years.
Plus you have the fiasco of that "State Farm" Ad that appeared with the Fury DLC until they removed it.
