Any wood-based cart updated after 2013 (or at least advertised working on 3DS FW 7.0) should do fine. Haven't tried Ace3ds+ but seems alright. I recommend personally: http://nds-card.com/ProShow.asp?ProID=507. It'll run anything you throw at it. And NO "timebomb". This is www.r4isdhc.com.cn and Wood-based carts like this don't have it.
