Hey, everyone. I recently came across an early build / prototype cart of Sonic and Tails / Sonic Chaos. It's supposedly a demonstration cart and I'm assuming that it may be similar to the Sonic 2 Game Gear prototype cart that was dumped not too long ago. The year on the cart says 1993. I'm not going to disclose any more information about the cart or who is selling it through this post though because of what happened last time with the CR Sonic Pachinko Arcade machine. That machine was relisted and we came dangerously close to obtaining it but unfortunately somebody beat us to it and bought it. If anybody is interested in buying this cart or know who I can contact to buy and dump it please message me privately through here and I will give more information.
This is already dumped, actually. http://info.sonicretro.org/Sonic_%26_Tails_Demonstration_Sample It shows up every now on then on Yahoo Japan, one of the more common GG demo carts out there. Unless you're talking about another cart, in which case I'd definitely want to see that. Speaking of which, going by the Retro thread linked on info page, it doesn't seem like anyone hacked into this one like the Sonic 2 one. Maybe there's more to find in there still?
Hmm but this cart was compiled one week AFTER the final retail game. So I don't think there would be any proto content in it.
Oops, I overlooked that bulletpoint in there. I guess it really was just a run of the mill store demo.
