By Hichako (ひちゃこ), ran from February 2002 to December 2004 in Famitsu Cube + Advance.
Roughly translated as "Hichako's Gaming Chronicles", Hichako tries her hand at various new Nintendo releases and captures her triumphs and foibles in manga form.

Episode #11 (Dec 2002)

Baby Hichako is carried through Super Mario Advance 3: Yoshi's Island and has her Yoshis fall on every possible hazard.

Based off Mario Kart DS, this is your typical over-dramatic racing manga, full of thrills, spills and dramatic close-ups - only with Mario characters. Also features the hunkiest Bowser I've ever seen. Like, wow.
