First known GPU miner to support upcoming Ethereum Classic's EtcHash algorithm.
Switching ETC mining from Ethash to EtcHash is hardcoded on epoch 390 (current ETC epoch is 383).
No special changes in config is necessary, minimal config for ETC is the following:
wallet = 0x9eab4b0fc468a7f5d46228bf5a76cb52370d068d
coin = ETCMining on Mordor ETC EtcHash testnet is possible too with the config like this:
[etchash]
; Wallet is set up in node, it doesn't matter what you write here.
wallet=0
; IP and port of your Mordor node.
pool1=127.0.0.1:8545
coin=mordor
