The final piece of extra content in the Nintendo DS version of Flower, Sun and Rain is rather uneventful, nothing like an English language option. It’s just a jukebox where you can sample the game’s tunes. A decent addition if you can listen to the songs while the DS is in clamshell mode. However, you probably can’t do this since closing the DS puts it in sleep mode unless you’re playing a GBA game or using the Play-Yan.
If you are planning to import Flower, Sun and Rain next week there are limited English menus, but a few snippets of familiar letters probably won’t mitigate the language barrier. I guess we’ll have to wait for someone to publish Flower, Sun and Rain outside of Japan. Perhaps, Rising Star?
