you haveto find them on your own but the original intent for freeshop was to use your Own dumped titlekeys to download games you own w/o needing to pop open eShop. considering its copywrited code (the encrypted and decrypted keys) plus the big titlekey database leads to direct piracy yea we cant share out in the open or PM's it just takes a short lil search thru google to find the URL you need to leave in freeshop
as about using CIA vers vs .3DSX? it matters if you give two S**ts about your private FCS_B getting banned easier or not. if you dont give two hoots about online play, then use CIA's online willy nilly, otherwise use the .3DSX version over using the installed CIA version.
