I have made a new version which fixes some bugs (but introduces others due to feature creep
Major addition is the ability to automatically make embedded pack200 self executing JAR files. This will on average give you between 50-100 extra bytes ON TOP OF any bytes gained using the 4KJO tool.
To use run the EmbeddedPack200.jar with no command line parameters to get help. *IMPORTANT NOTE* since it is a very brittle tool you may have to launch the jar from the same directory where you have extracted all the files to.
Also, it is best to steer clear of the JShrink option in the 4KJO tool as it has not been correctly implemented.
The new version can be found at:http://www.sharebigfile.com/file/55424/4KJO-7z.html
You may need 7-zip or the latest version on winrar to extract the archive.
Let me know if you have any trouble using the new tool.
