Peeps are using STHS V2 Client for Mac and Linux Only : Version 2.2.2 - Release the 2013-09-08, right?
This is the file I'm unable to unzip...
[LATER]
Sigh. Unzipped now, thanks to Kershaw's Keka archiver program. Still no dice. XQuartz, Mono both installed, Client unzipped and .exe file moved to douglasemerson, league file downloaded and moved to douglasemerson. Open xterm, type "mono SimonTHockeySimulator.exe", get an error that says "The entry point method could not be loaded".
I am teh suck, apparently.
