How do I create a new genesis block for an altcoin? I'm trying to clone the Blackcoin sourcecode just for the hell of it but I can't seem to generate a genesis block. I can do it on normal coins, but not here. The Blackcoin developers seem to have shifted a lot of code into weird places. 

For example, all of the coins major parameters are in chainparams.cpp. However, there is no code in the link above or in main.cpp to create a genesis block.

How do I make a genesis block for this coin?
They just removed the gen-generation part from the sources as it's not needed after the genesis being generated and already implemented (hardcoded) into the sources.
