So I was only able to load up the Super Mario floppy disc, I have no clue how to operate so I couldn't fully test I did play Super Mario world works as it should. Missing 1 of the top doors probably could be 3D printed the extra floppy disc I could not get them to load maybe I am doing something wrong but they are included along with everything else shown. Can't find any comps if you have any questions I'll try an answer the best I can.
