Here it is! My 2012 7DRL, I rule, you rule, we all rule old-school Hyrule. I no longer have it running from this page since so many people were having problems with it but you can still download it and run it localy.
Download the iryrwarosh.jar:
Once you have the jar file, double click it or type "java -jar iryrwarosh.jar" from the command line.
2012-03-23 update: I made a minor bugfix that was causing an infinite loop when a monster tried to unhide but couldn't find an acceptable place. This doesn't change the gameplay except it's now theoretically possible to kill something that's hiding by blocking the only places it could enter again.
