2012 is an update for Super Street Fighter 4 Arcade Edition. Minor tweaks and adjustments have been made to nearly every character, while other characters such as Gouken, Yun, Yang, Evil Ryu, Fei Long and Hakan have been significantly changed in order to address global balance issues.
If you have the older Super Street Fighter 4 software and want to have the latest edition, we can have your HDD upgraded. What this means is that you need to send the Super Street Fighter 4 Japan Edition HDD and security dongle to our warehouse, where we will send to the factory for upgrading to the latest edition.
