Check out this YouTube video
https://www.youtube.com/watch?v=ENaTmbh8XuwIt's actually #2 in a series of 6. I think in this one he discusses what you need to do to generate the genesis block.
Might be in a later one, but they are all short videos that you can watch to see if you missed anything.

Thanks, I know this video(saw all 6 before), saw this before for Scrypt based Litecoin.
I need SHA256, After google, found few generators (GENESIS0), but this will generate one at time MainNet or Testnet or regression.
Which will have different epoch time, Merkle, Geneisblock hah etc.
But In Bitcoin, Litecoin or any other coin all the 3 nets(Main, Test, reg) have same Merkle and Epochtime.
Using Chainparams.cpp It will generate 3 Genesisblocks(Maine, Testnet, Regre).
How to do in that way.
