Yes, actually mGalaxy filter options are based on the 'catver.ini' category names of the
english file (that one can find on the same
http://www.progettoemma.net/?catlist page).
I tell you how it works inside mGalaxy (the rules) so that you can eventually adapt your catver.ini file to make it work with mGalaxy:
Filter roms based on their genre name, if:
Genre STARTS with 'Fruit' (ex: Fruit Machines)
Genre STARTS with 'Electro' (ex: Electromechanical - PinMAME)
Genre STARTS with 'Tabletop' (ex: Tabletop / Othello)
Genre STARTS with 'Quiz' (ex: Quiz / Japanese)
Genre STARTS with 'BIOS' OR 'System' (ex: System / BIOS)
Genre STARTS with 'Not' (ex: Not Classified)
Genre CONTAINS 'Mature' (ex: Puzzle / Match *Mature*)
So, for example, if you would work with the french version of catver.ini (
http://clrmamepro.free.fr/catlist), here are the changes you would have to do inside that file:
Fruit : no changes, the same genre name for both languages: Fruit Machines
Electro: change '
Électromécanique' to '
Electromécanique' (without the accent)
Tabletop: change 'Jeux de Table' to 'Tabletop' (or 'Tabletop (Jeux de Table)' for example)
Quiz: change 'Questionnaire' to 'Quiz' (or 'Quiz (Questionnaire)')
Bios: change 'Bios' to 'BIOS'
Not: I can't find the equivalent 'Not Classified' roms in the french file...those roms are not listed inside
Otherwise you should replace the genre name by 'Not Classified'
Mature: change 'Adulte' to 'Mature'
I hope that it'll help you!
