A bit light on the details, but we enjoyed seeing this video out device for the Nintendo Game Boy. A parallel cable connects to a modified Game Boy and transmits signals to the adapter which is housed in an old VHS cassette. We gather that some Super Game Boy hardware does the signal processing but from there your guess is probably better than ours.
[NeX] mentions that he originally wanted a screen to be included in the cassette. We’ve seen custom portables with small screens before, but he’s also developed a bare bones hand-held without a screen so that’s where the inclusion in the cassette would have been handy. We also wonder how the images will look on a big TV of the 50+ inch size. [NeX] has been pretty busy with the hacking lately, don’t miss the wire porn of his homemade Game Boy project.
