Motorola, which is scheduled to make the announcement at the JavaOne trade show in San Francisco, worked with Sega to develop an application program interface that allows game software writers to develop games for mobile telephones, says Miako Shimizu, a spokesperson for Sega Enterprises in Tokyo.
The API works with the Java 2 Platform, Micro Edition developed by Motorola and Sun Microsystems.
J2ME is designed to increase wireless access to applications by not requiring that one application be rewritten to work on various wireless devices.
Motorola and Sega have announced a partnership to bring a "wide assortment of entertainment software" to Java-enabled phones, pagers, and personal digital assistants, according to a statement made by the companies earlier this week.
The first such Motorola phone will also be unveiled at the exhibition and is scheduled to go on sale in spring 2001 in the US, the Sega spokesperson said.
The new games will be a generation above the basic games and animated images currently featured on mobile phones, the company says.
