Ya I noticed that I sent a message to the vendor to ask.
I might just use switch cases and hot glue the small plastic sd card cases in. Between CD's, DVD's, and SD Cards I think the SD cards would last much longer and easier to keep the files updated.
I can kinda do this with my steam library too just would have the DRM stuff would just be the game files not the install files.
But would be nice to have some kind of physical copy.
