As some of you might know, Sega Genesis and Blockbuster worked together in the mid-90s on flash carts, called New Leaf, where a customer could go into Blockbuster and request a game to rent, which would then be flashed on a cart that could be re-used. I think the best description of the history I've seen can be found at this link here:

The product made it into a test run of 10 local stores in South Carolina, but never made it past that because major record labels did not want Indie labels on an even playing field (the idea was to do this for not just video games, but movies and music, as well). Until recently, only a handful or so of these New Leaf cartridges were known to exist. As is the case in our hobby, Enter a random Florida swapmeet.
I don't want to tell someone else's story for him, but suffice it to say some woman pulled out a bunch of funny looking Genesis carts and another person at the forum, himself an ardent retro collector, made a swap. I don't know the exact number, but all in all, he found maybe 6-8 New Leaf carts, with varying games on them, which had the titles of the games written on the top label. If you peruse Ebay for these kinds of items, you've undoubtedly seen five or so pop up the past couple weeks. But then he put up another group of items, which made me change my thinking that these items came from one of the ten stores.
Best I can tell, these appear to be prototypes of...the prototypes! Some of the boards are the same as the New Leaf or Game Center carts, but the Pebble Beach and Zombies Ate My Neighbor carts appear to be Frankensteined, possibly as the New Leaf developers figured out how to get the system working. All I can think is that the woman who had these found the in a storage locker from one of the developers.
Anyway, I'm sure it's nothing to a majority of gamers and collectors out there, but I thought this was really cool. It tells a bit of a story that is still a bit of a mystery in the Genesis and I guess Blockbuster communities.
