Video game giant Sega Corp. officially announced Wednesday it will halt production of its loss-making Dreamcast game console by the end of March and shift to game software.

The company also said it has revised down its earnings forecast for the current fiscal year that ends on March 31, due mainly to losses related to Dreamcast.

Sega said it will provide software and game-related equipment for other companies' game consoles, including Nintendo Co.'s Game Boy Advance and Sony Computer Entertainment Inc.'s PlayStation2. It will also continue to sell Dreamcast titles.
