Super Mario Wallpaper Maker (opens in new tab)

To make the image, click the robot. To select other resolutions go to the main page and click the monitor or smartphone.

Any thoughts as to why Mario is not moveable?

I just found two secret parameters.

To get two extra items, namely ghost and star, append &opt=6358D569C9 to the link. Or use $('body').addClass('secret') in console.

To replace Mario with Toad (only in SMB), append &opt=7F93F702E6.

By using the latter opt, and adding secret manually, you can have both.

I made one. http://mariomaker-wp.nintendo.co.jp/shareImages/cd6a8db28ca6...

Ah.. reminds me of this Mr Robot Apple game - https://en.wikipedia.org/wiki/Mr._Robot_and_His_Robot_Factor... where i can design my own maps..

If you use the mushroom you can not only make Mario larger, but other objects too.

All this time I was trying to figure out how to run it but then spotted the "Wallpaper Maker" in the title. Sad layfe :(

This is surprisingly fun! I just wish they had made the page available in some non-Japanese language (even French would do).

My kind of playground!
