So I recently opened a blog-post about free Nintendo Cia Files. I got these games :

Pokemon Alpha Saphire
Pokemon Omega Ruby
Pokemon X
Pokemon Y
Pokemon Sun
Pokemon Moon
Pokemon Super Mistery Dungeon
Super Mario 3D Land


Give my Blog a try. You aren't going to immediately be downloading all the files. Meaning you can just watch it and when you decide to get those games, simply click on the links.
Further instructions are on my Blog Page
