Nov. 28 (Bloomberg) -- Nintendo Co. isn't delivering enough Wii video-game consoles to meet soaring demand and will ship more this weekend, the head of its U.S. unit said.

``We don't have enough out there,'' Reginald Fils-Aime, President of Nintendo of America, said in an interview. ``We're going to put more products into stores going into the weekend.''

Nintendo aims to sell 4 million Wii units this holiday season and is trying to ship 250,000 machines a week as retailers sell out. Sony Corp.'s rival PlayStation 3 console sold out in minutes after it went on sale Nov. 17 and replenishing them has been limited by production snags.

Some Wii machines have been unable to connect to the Internet, which allows users to download new games, Fils-Aime said. Nintendo is replacing those with new units, he said.

Nintendo said yesterday it sold more than 600,000 Wii consoles in the Americas during the product's first eight days on the market.

Shares of Kyoto-based Nintendo fell 420 yen to 26,010 yen today in Osaka trading. They have gained 83 percent this year.
