I'm using many VICE configurations and VICE have in 3 separate folders for some command line not accessible options.
One reason of them is not existing command line parameter to change internal or external function ROM of C128.
Very useful will be to add this option to command line 'cause it reduces my VICE three folders to one.
Also various configurations is possible to set by registry editor (Windows platform) for context menu instead to creating shortcuts with parameter %1%, more useful and more elegant.
If anyone don't know how to add own items to context menu (Windows platform) let me know I add it as reply in this thread.
