I am running the games from the preloaded microSD card and I am looking on the Tinycircuits Web site to find the files to download to the microSD.  Help.

Oh, forget it.  I found it through the Kickstarter site.  https://tinycircuits.com/pages/tinyarcade.
And it looks like my preloaded micrSD had all the same games at this URL plus two preloaded videos.
