Mother (aka Earth Bound) is a RPG developed by Nintendo Tokyo Research and Development Products in cooperation with Ape, published only in Japan for the Famicom in 1989. Thanks to OKeijiDragon and GlitterBerri, we are able to have a look at an old beta video, in wich we can notice many little differences in the beta version of Mother.
Originally found on Nico Nico Douga titled, ファミマガ Ｖｉｄｅｏ 【 1989年 ５月号 （２／２） 】 (literally Famimaga Video May 1989), I stumbled upon this interesting Mother footage while searching for media on Mother 3 for Shat-Canned Legends. Same as the SMB3 footage.
The video shows the various differences of this prerelease version to the final version that my annotations go over. While there isn’t anything hugely major to show, the path from Ninten’s house looks to be mirrored, some game menu details are different, and the O on 0:07 is at the lower right corner of the title!
