I initially was interested in this project, but finally, to my mind, i'm afraid it won't be possible to have one controller able to correctly handle the various types of boats we have in ship sim.
For example, I don't believe joystick axes on our computers are able to work over 360°, like azimuth propelled ships need. I don't think this has to do with the game programming nore with the controllers, but simply with the way Windows handles joystick axes. The only solution to handle this correctly, to my mind, would be to developp a specific usb controller (not considered as a joystick) that ship sim would natively recognise. But maybe I'm wrong on this point.
So, it's not only a controller at 199 euros that would be useful for only one game, but i'm afraid it's controller that would be useful for only a few ships in one game. Agile Solution, PoR, for example. But it won't be able to handle correctly Bugsier2, Red Eagle, or Ocean Star ... It won't even be able to handle a sherpa, as the sherpa has one bow and one aft thruster, and this controller only seems to have one thruster control !
about the question 'will it be compatible with ship sim 2008', or about the fact mentionned by Minime that it would not be able to handle two motors because the levers are made with different colors : you don't have to worry about that, we're just talking about a big joystick, recognized by Windows, with different axis you can assign with the control menu of ship sim, regardless the version (2006 or 2008).
And about the fact (as Chris-S1 initially asked) that this controller could make the game run faster or slower, there's no way a controller might have an impact on the performances of the game.
Hope my english will be understandable :-)
