Answer
During the installation of ROMES, the option file gives you the information on the options (especially hardware drivers and export filters) that are allowed to use. And only for these options the corresponding files will be copied to the hard disk. To add new options you have to make the ROMES installation once more, using your new option file, and then the missing files will be added automatically.
During this installation the option file will be copied to the application directory automatically and overwrite the old one.
