This will clearly be fixed with next version!!
1. We wanted to avoid roms named "pacman.zip", "pacman(beta).zip, "pacman(v2).zip" to be displayed "pacman", "pacman", "pacman".
That's the reason why the name of the rom was always used for the description (apart from Mame, of course)
This will change with next version: the user will have the choice to display the rom name or the description (given by the web server DB)
That way, "Donkey Kong Country 2 - Diddy's Kong Quest (Europe) (En,Fr) (Rev 1)" wil display "Donkey Kong Country 2 - Diddy's Kong Quest"
2. You'll get the option to clean the description name too, removing parenthesis and brackets
That way, "1942 (Revision B)" will display "1942"
