SEGA Ages Sonic the Hedgehog 2 is releasing in the west soon, but thanks to it already being out in Japan, we have footage already.
You can see the video below.

In addition, I would like to add that there is an active Sega retrogaming Facebook community group you can join at https://www.facebook.com/groups/segaretrogamers/
