Texture from super mario bros

Thanks for this! Where did these images come from originally? Are there any copyright/licensing issues with using them?

I'd prefer for #31 to be added since those sprites are original and there's no possible copyright issues with them.
The current textures are from Super mario bros and after a google search it seems that Nintendo can copyright for using those textures :(
