That's cool. Unfortunately my frontend still needs category.ini for MESS (category_home.ini) so non-arcade machines without software lists can be properly tagged... machines with software lists can be easily tagged as non-arcade (category_home.ini not required)
I can add support for catver_full.ini and show its info if 'category_home.ini' and/or 'version.ini' for MESS are not found.
... update ... DONE! If you have catver_full.ini it will be used instead of catver.ini. File version.ini for MESS is not required then. But if you want non-arcade machines without softlists properly tagged as non-arcade you still need category_home.ini.
... or you can just use the regular catver.ini together with category_home.ini and version.ini for MESS (for faster access)
