Yup, GBAtemp does not endorse piracy (seriously, it really doesn't). x'D
Anyway, it's not that hard to find working links, you just need to do a better job at searching.
Or you could be a good lad and decided to download the demo's from the eShop and if you like the game, buy it. =P
Just kidding, seriously though, it's not allowed to give links so yeah... This will get closed by a mod soon enough.
