That seemingly omnipotent Japanese publication have screens, and if you can read Japanese, information for you to see!

There are screens of the following DS games;

Another
Super Peach DS
Touch! Kirby DS
Mario Kart DS
Harvest Moon DS
Animal Crossing DS

Bear in mind none of the titles of the above are actually confirmed as the final titles for the released games. Looking at the screens though, many of these games seem to be nearing completion, and making some novel use of the DS stylus. Most notably perhaps Harvest Moon's ability to wash animals!
