Sound is eliminated on some software titles when played on the PS3, while some other titles do not play on the latest machine at all. The PS3, launched in Japan on Saturday, is supposed be compatible with game software designed for its previous models. Sony shares were up 0.9 percent at 4,730 yen by midday, underperforming the Tokyo stock market's electrical machinery index (.IELEC.T: Quote, Profile, Research), which gained 1.72 percent. Shares in rival Nintendo Co. Ltd. (7974.OS: Quote, Profile, Research) were up 1.4 percent at 26,070 yen. Satoshi Fukuoka, a spokesman for Sony Computer Entertainment, said the game unit of Sony is checking the compatibility of the PS3 with some 8,000 game titles launched in Japan for the PS and PS2, but declined to give the number of games found incompatible so far. The Sankei Shimbun daily said on Tuesday about 200 PS and PS2 titles are likely to have compatibility problems. Fukuoka said Sony plans to solve the problems by online upgrading of system software for the PS3. By the highly anticipated PS3 launch, Sony is pitting itself against Microsoft Corp.'s (MSFT.O: Quote, Profile, Research) already available Xbox 360 and Nintendo's Wii, which will hit U.S. stores on Sunday. Sony plans to start rolling out the PS3 in North America on Friday. Gamers in Europe must wait until March due to a glitch in commercial production of blue laser diodes, a key component of the game gear's Blu-ray high-definition DVD player. Sony sold 88,400 units of its PS3 in the first two days of the Japan launch, leaving most stores without any stock, video game magazine publisher Enterbrain said on Monday. Sony aims to ship 6 million units of the PS3 by March. © Reuters 2006. All Rights Reserved.
