Well from my point of view, the Dolphin emulator isn’t technically that legal but you wouldn’t ever be caught or get in trouble for using it, plus it is an easy and cost effective way to play population growing. I’ve always played the game on the first edition Wii that was backwards compatible with GameCube games, all you need is a controller, the game and a memory card! It’s a shame you’ve reached the limit but you can totally send your friends FC over and I’d be happy to play with her! Of course if you were looking for more easily attainable copies of AC it would be City Folk. You could still probably get a GameCube fairly cheap depending where you are in the world.
Population growing is very similar to ACWW. However there’s lots more thought put into the smaller details of the game, like lots of events in between big holidays to keep you occupied and you will always have at least a couple errands to do a day. You still have Nook’s Cranny, Able Sisters, and the post office, however it takes a moment to realise you don’t have a Main Street if you’re so used to playing NL like me! xD It’s one of the best titles with so many more villagers, but it’s not short of it’s bad points - like the storage issues etc. I can always inbox you some YT videos for you to watch to get a better sense of the game if you like! ^^
