It looks like United States gamers hoping to play their PSP games on their PlayStationVita will be disappointed as Sony has reportedly told Kotakuthat the PSP UMD import program won't be available for American gamers. This means PS Vita owners in the United States will be unable to play their older PSP games unless paying for it again.
Currently available in Japan, theUMD Passport program lets PS Vita owners download PSP games they already own from the PlayStation Store by inserting the game into the PSPand registering the product online.
All hope isn't lost for backward compatibility, however. The PS Vita will play will play all PSP games purchased digitally through the PlayStation Store, including Minis and PSOne Classics.
I have to say this is an odd move on Sony's part. Given thepoor sales of the PS Vita in Japan, you'd think they'd be eager to include as many addedfeatures as possible with the U.S. version of the Vita to help boost sales.

看起来很多在美国的希望能用PSvita玩PSP游戏的玩家会感到失望了，据报道，索尼公司已经宣布PSP的UMD导入程序，将不会为美国玩家提供。这意味着在美国，除非持有者将要再支付一次游戏的钱，否则PSvita无法发挥玩PSP游戏的功能。
目前在日本，“UMD Passport”计划让允许vita的持有者下载那些他们已经购买过的PSP游戏从自己的PlayStation Store上转移到PSP中并且在线注册这些游戏。
但是向后兼容的希望还是有的，PSvita可以玩那些从PlayStation Store购买的游戏下载版，也包括MINI游戏和PS游戏。
我不得不说这对于索尼来说是一个奇怪的举动。由于在日本的PSvita销售不佳，你本以为他们会急于包括在美版添加尽可能多的附加功能，以帮助促进vita的销售。
