This will allow my to use the explorer but the currency is labeled "Hirocoin", while all transactions and blocks appear to be from Logicoin. If I change "loader": "Logicoin" then it shows 0 blocks and doesn't work at all. Not sure what I've missed?
Leave "loader" as "blkfile" and "policy" as what it was when you could browse the blocks. Add "chain":"Logicoin". If you omit "policy" it defaults to the chain name, but Abe does not recognize "Logicoin" as a policy name. (Ideally, we should tell Abe/Chain.py about Logicoin.) If you specify "policy", then Abe uses the chain name for display and search only, so "chain" will not affect the block count or content.
