Rather wanting to support .kjx files, however adding support for that would mean adding it in the Java emulators and RatufaCoat as well. So I suppose what I should do then is add a kind of emulator layer handler that can access given files or otherwise as if they were libraries and otherwise. I would say that I would have to implement it like service loaders and wrap on top of the existing shelves and such. I suppose if a JarPackageBracket is indicated to be in software it can be forwarded to the software layer. Of course SquirrelJME really only needs the openResource() to be implemented. Implementing it for the Java emulators would probably mean writing my own ClassLoader possibly or just loading the entirety of the JAR? Not sure there yet, but I should design it with SpringCoat and RatufaCoat in mind first.
