Understandable, but disappointing. There already are emulators for the software. For the real experience, I'd like to type using that clunky C64 keyboard :P
Nintendo has sold a great many NES and SNES Classics with non-working cartridge drives, and I'm sure a lot of the people buying those were geeks, so it must not go too strongly against it.
This is weird... Why would I plug a keyboard into what looks like a perfectly good keyboard?
