Super Street Fighter II X for Matching Service (Dreamcast) - Gameplay as Tien Gouki

In this video, I play the Dreamcast port of Super Street Fighter II Turbo/X. It is an arcade-perfect port that brings a few new features such as multiple game modes and customization options.
One of the additions to the port is the option to play as the boss version of Gouki/Akuma (known as Shin Gouki, due to having double air fireballs) as well as an even stronger version nicknamed "Tien Gouki", that has a super meter and therefore can perform the Shun Goku Satsu. Normal Gouki and Shin Gouki don't have super meters and you were only able to play as the normal one (without double air fireball and super meter) in previous versions of the game.
Shin Gouki and Tien Gouki are unlockable characters. The way to do that is by accessing the hidden DIP Switch menu and enabling DIP Switches 27 and 28. For more information about this menu, search on GameFAQs.
