This screen is taken from a video recently uploaded to YouTube by user DeChief. DeChief contacted me through the Assembler forums to ask if I would be interested in seeing a video that had been digitised from an old Japanese promo VHS tape. Naturally, even with overtones of the film Ring, I was keen and upon viewing it I realised the video was one I'd never seen before.
The second half of the upload busies itself with game previews (and includes footage of Geist Force); but it's the first half that offers up the good stuff. At the 3:45 mark, the video shows off some intended uses for the VMU which include being able to attach the device to an arcade cabinet, the VMU attached to a mobile phone, and a VMU stuck in a hi-fi mini system!
