The only way to do it right now is using an external .ini file to filter the list. AntoPISA created one called category.ini for MESS (renameSET page). My frontend Emu Loader will use this file to tag games as arcade and non-arcade so they can be filtered. That's the only way to do it and I hope this doesn't change in the future. Note that the purpose of this new "machines" filter in Emu Loader is not to filter out all non-arcade machines, but to be able to choose what appears in the games list...
