from what i understand the game got recalled because of problems with the new steering wheel.
here is a quote from GAMESPOT.
"According to the companys news release, gamers using two models of Logicool steering wheels have experienced two problems: first, the accelerator doesnt go to 100 percent, and second, after turning, the wheel cannot be returned to center (turning the controller wheel doesnt affect the onscreen steering). Sony has invited gamers experiencing this problem to mail in their game discs for a replacement.
Logicool is the Japanese name for peripheral maker Logitech and the affected products are the GT Force and the GT Force Pro aftermarket steering wheels for the PS2. SCEJ is treating this issue as a software problem, so there is no indication at this point that these wheels will have problems with other games, or that U.S. market Logitech products will be affected. Moreover, SCEJs news release confirms that this bug does not affect standard Dual shock controllers.
Currently, there are no plans to release Gran Turismo 4: Prologue Edition in North America. The full version of the game is due out in April 2004. "
here is a quote from GAMEINFORMER
"Sony Computer Entertainment Japan announced today that they are recalling copies of their just released title Gran Turismo 4 "Prologue" due to some issues regarding the game's performance when using certain models of Logitech's racing wheel.
One of the bugs only allows games to reach a maximum of 99.6% of their top speed, while the other glitch causes the racing wheel to fail to recenter itself due to a fault in the game's force feedback programming.
For those of you who imported the game and are having problems using a Logitech wheel, you may just have to suck it up and made do. Japanese gamers, however, can return their discs to Sony and get a replacement that has the glitches corrected."
here is a quote from PSX EXTREME
"Sony Computer Entertainment Japan has announced a disc exchange for customers affected by controller bugs in the Gran Turismo 4 Prologue, which is currently on sale in Japan and fine import shopes everywhere.
The company has said in a press release that gamers using two models of Logicool (Logitech over here)steering wheels have experienced two problems: first, the accelerator doesnt go to 100 percent, and second, after turning, the wheel cannot be returned to center (turning the controller wheel doesnt affect the onscreen steering). Sony has asked gamers experiencing this problem to mail in their game discs for a replacement.
Given how closely the GT4 creators work with the people at Logitech, it's surprising that such major issues exist. Certainly this problem will be cleared up for the final relase, but check back here for any more big GT4 news."
