Problem with genesis block replacement

[BlackHatCoiner]

I want to replace Satoshi's genesis block with mine. I've generated a valid hash with Genesis Block Generator, but I'm getting this error once I run the compiled bitcoin-qt.exe:

Here's my block's information:

Code:

Hash: 000000003a7385e7dae9000662e5867c9330386f627d7b4e54386d9fe8d3d488
Nonce: 3407408574
Unix time: 1617893414
Public key (Uncompressed): 043b41c76ed8826d0341f82ac92c607c943fb8bfb5074ee4fbb0aab578369854e13e9ce3ff2318dfbb69bf30b9c5e4153b4bf6ab3c3396344d1501e42c19113afe
Block message: "3 September 1974, the foundation."
Merkle root hash: 148e8dd6467cd80a4aa037cc8931a4ee0e05b38bdb5b723ace9cd7212d525424

These are the modifications that I've made on chainparams.cpp: [Link]. What exactly do I do wrong?


Edit: Fortunately, I found the solution by myself. I didn't know that you'd have to replace the genesis.hashMerkleRoot with the byteswapped result. I believed that I should have put the merkle hash from the genesis block generator in there. What a happy ending.
