You may or may not know that when Capcom USA Coin-Op was in business, we purchased quite a bit of merchandise from them, so our knowledge of what is and aren't legitimate releases is pretty solid.
To be specific, SF AE is a true Japanese release only. The chips were sent to various countries, mostly Asian, making the item a Japanese converted board with English text. There is no US version, since Capcom Coin-Op was out of business during this release. We inquired with Capcom USA about these boards and they specifically told us that there is NO official US release. They offered a party outside the US to modify the board with Japanese chips to have the text translated to English, but again, this doesn't make the release a true US release.
