i've changed all names to 'Card Captor'
http://redump.org/discs/quicksearch/card-captor/
previously each of 3 games had slightly different variation:
'Card Captor', 'CardCaptor' or 'Cardcaptor'
my reasoning picking that particular variation being that 'card' is a word and 'captor' is a word
whereas 'cardcaptor' is not a word
but i'm not familiar with anime, maybe it's actually used like that there
so maybe one of those two alternatives is better?

official: CARDCAPTOR (inseparate & uppercase, I couldn't find the capitalized title.)
