So TonK's big secret is....
The discovery of three English AES copies of Aero Fighters 3, making this the rarest English Home Cart!
The story behind the find is in this thread over on N-G.com, and the news has already hit Kotaku.
Now while this isn't the most exciting news in the world for me personally, the fact that this contact used to work for SNK is. I'm hoping that there'll be a lot more to be revealed over the coming months.
