The English translation of the menu software for the Nintendo GB Memory flash cartridge is released! This patch translates all Japanese text into English, with the exception of the stylized “News” ticker at the bottom.
Available in Japan from March 2000 to Sept 2001, the GB Memory cartridge was an official Nintendo product that could be flashed with multiple games at kiosks available in department stores.
Hacker orangeglo has been working with the GB Memory Multi Menu ROM for some time, creating a website (GBNP) that allows users to build a new menu ROM with the games they desire.
