Go! Go! Kokopolo, which I consider to be one of the best DSiWare games out there, has receive a update version for those who previously purchase the title on the Nintendo eShop. The update version requires an additional 170 Open Blocks on your System Memory. I don't know what the update version does but I can't wait to find out.
Note: It's not available at the Update section from the Settings/Other, it's at the Title Info.
