The nintendo demo vision is an interesting piece of hardware. Used with a special gameboy that has a cable run from points on the cartridge connector, it is somehow able to translate the eight pins into upscanned and upscaled composite video with mono sound. The quality is remarkable and is far better than super gameboy. No borders, just full screen gameboy on any size TV. Some of the units are configured in dual gameboy configurations. From what I have learned, they are generally used to avoid eye strain while testing games, and were also been used at trade shows. Feaures of some models are: timer until reset, sometimes multiple video out for video wall, gameboy advance and color models. I've run into several different types, and will have a more detailed article in the future.
so assembler are these the units that were used in the old big gb kiosk where you played the game on the the gb and also displayed on a sharp novelty size gb in front of you?
I wasn't aware a demovision output in fullscreen, I thought you'd get like a gameboy graphic with ascreen on the screen and then play in the screen. Secondly to the question above, from a hardware standpoint they may have been the same, get one of each do a compare but I I'm not sure what that other unit you're talking about is.
Well there seems to be a lot of variation in the twenty or so units I have. Some have no markings, some are marked, some singel, some double, some modded, some say gameboy vision, some say demo boy, demo boy II. It seems these are very small volume items, and are made to order. I even have a PAL one.
I'm looking forward to hearing more about them when yopu have time. Any chance of a few shots of one running on a TV? Also, did I read right that it works for GBA too? How about GBA SP or DS via the GBA cart port? Yakumo
