video game Phantasy Star Online Episode I & II had a duping glitch, which was activated by talking repeatedly with a walking NPC and a merchant. Because the characters and data of the game were saved on memory cards, SEGA could not remove the duping glitch, and the online game was filled with duped items and money. In the Xbox 360 game Forza Motorsport 2, there was a duping glitch which enabled the player to sell car upgrades they had not yet purchased. By selecting an upgrade, and quickly pressing X, the player is able to have the option to sell the upgrade, without having to buy it first. This caused the Auction House to become flawed, because players who had earned their money via the glitch, were able to out-buy players that only had money they have gotten through races. There is a patch to fix the glitch, but players can still perform it, and transfer the money onto another account. In the PlayStation 3 game Gran Turismo 5, there is another duping glitch that requires two separate PSN accounts to use. On the main account, the player can copy the save file to the game to a USB flash drive, then the player can perform trades to the alternate account. The player then backs up the save on the main account, and makes the trades again to the main account. However, while the amount of trading is unlimited, only one car per game day can be traded, but up to five paints and vehicle upgrades can be traded per game day. This has been used to get high level vehicles from Random 1000 tickets, such as the famous Red Bull X2010 Prototype, and Level 21-24 tickets while gasoline prices continue to gain during the fluctuation.
