I recently picked up a VHS that promotes the CR Sonic Pachinko machine that was released in 2003. The video includes some background on the Sonic franchise and features several segments showcasing the pachinko machine in action, giving a glimpse of what the gameplay looked like. (Link just in case it doesn't embed) I also scanned the VHS and sleeve which you can find here. The original video is on there too. It's nice seeing the SA2 models in action. I really loved how everyone looked (minus Amy) in that game.
I didn't even think about that. A while back there was one online for a long time but the proxy services I used didn't want to buy it for me. The seller finally put it on ebay and it didn't last long there so I missed out. Your comment does make me think if there's hidden stuff like in other pachinkos.
