I would guess that those items do not qualify to be added to the site's database, however if, the other way around, they are programs designed to be used in videogame consoles such as Family BASIC for the Famicom, Netflix (released only in Brazil as a bootable disc) for the PS2 or OtherOS (Linux) for the PS3, I believe they can be added to this site.
But this is just my guess...
