...Since Version 2.8 support for OPL2/OPL3 emulation was added to play AdLib ROL-Files, LAA, CMF, DRO and SCI files.
To start the player you may just double click the jar or use: java -jar ./javamod.jar or (for just commandline) java -cp ./javamod.jar de.quippy.javamod.main.CommandLine.
This player can be run als a console application, with its swing gui. The formal applet support is gone. Applets are not supported in most browsers anymore.
