After getting the game I first tried to install it via wine. It worked but the sound did not, at least not properly. So I consulted the online world for help and found out that you can install it natively on the mac - its java baby.
Get the
inofficial java installer, install the game to ~/EdnaAndHarvey. Now you can play the game from console by cd-ing to the install dir and typing
java -Xms256M -Xmx512M -Dsun.java2d.opengl=true -jar EbaMain.exe w
If this gives you some error-trace "bad version number in .class file" you have to switch the java-version to 1.6. You may start it by typing
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Commands/java -Xms256M -Xmx512M -Dsun.java2d.opengl=true -jar EbaMain.exe w
For enhancing the comfort when starting the game you may also write a bash-script or even better:
Bundle it to an app using
platypus.
Paste the line above in a new script, open the hardy icon in preview and drag it in platypus' icon-field, set output to none, uncheck "Remains running after initial execution" and dont add anything to bundle in with yet - or it takes you a long time to pack. After the app has been created open it with a right-click and "show package content..." copy the content of your install-folder (~/EdnaAndHardy) to "Contents/Resources". You can delete the jre1.6.0_06 folder, which will save you about 80 Megz, thats not much compared to a 6.6 Gigz game, but it wont hurt.
Enjoy the game...
