well i used to use nds flash carts to backup my games so i could take them out with me, without needing to carry my actual game carts with me to college. now i have a 3ds xl since the release of it in eu and its on ver.9.0.0-20E, i'd like to use gateway but people keep saying 4.0.5 is the only one that works. gateways website says they've updated it so it works with themes now,which came with the latest firmware update so this has confused me. i dont want to buy a gateway if i can't use it on my 3ds xl, because finding a console with older firmware is going to be mad hard around the local high street shops where i live, especially because everyone has internet and they connect everything they own to it. any guidance to places where i may find a older firmware console or the real facts of gateway will be great.
