Be careful downloading the wallet posted on that site, as it has strong indications to be compromised! Virustotal finds 17/52 - which is considerably high, as most wallets show no signs of viruses at all.
It seems the author deleted all traces of the old wallet (perhaps no viruses) from all sites about Emeraldcoin. The only wallet I could find was on the above mentioned site.
