I thought everyone might like to know there was a new cover version of 'Ottodokkoi Nihonbare' released recently.  On a collection of chiptune versions of anime themes, Picomoe! Future8bit Series 3 ~8bit de Mirai Ryokou~.  Arrangement by Iwano Michiro, Vocals by Masako Ookouchi.  There is a brief clip at the site (track 11) though it doesn't really do the full version justice.
