When I saw that price I would have bought it even if I didn't want it. Ha. Again it was many years ago, sitting on the top shelf at a store before it moved into a smaller place where they began focusing on comics and CCG's over gaming and airsoft/paintball. They weren't the valuable games, stuff like pinball, tennis, or boxer. I had to go online to find my faves Wario Land and Panic Bomber. Now that retro is popular and collecting has become a thing the VB has risen in value. Plus you can say it's Nin's only actual failure.
Lol, no I didn't take it that way. It's easy to make jokes about it. Lots have interest now, especially if the homebrew market continues. In that second pic you'll see something called the Flashboy. It's a flash memory cart that lets you play translated import games and all the rest on actual hardware. I probably don't have to tell ya this is one of those platforms you really can't emulate on a PC.
You know I don't ever recall seeing a demo unit. Speaking of which those are very collectible if you can find one.
One last thing. Is your VB working well Twiz? After years of light use I set it up again when I found that homebrew site. I guess there's a problem with the glue that holds the ribbon cables to the LED's and eventually it gets glitchy. I sent mine out to be repaired since it was finer work than I was used to doing. Just something to be aware of for later.
