Request: Alpha 1.2.2a Generation

I think it'd be really cool to have 1.2.2a's terrain gen in this mod so we can generate the iconic pack.png hill. Currently the closest to this is Beta 1.1_02, which is close, but not the exact same.

Due to how feature placement works in modern Minecraft, I don't think this is possible with the code as is without a whole bunch of world gen trickery.
