First off I'd like to notify you all that I'm a complete dumbass when it comes to things like hacking and using nintendo products, so please excuse me or "dumb it down" when you're talking about certain terms. So I've recently been viewing ebay for a 3DS XL when I saw a cheap one that also included mario kart 7, I was happy with the sellers reputation and decided to do abit of research before I decided to buy it. That's when I noticed the 3DS XL had a region lock with it. I currently live in Australia and the 3DS I wanted to purchase was from the US, this was sort of a good and bad thing. Also if you could put the number first so I know which question your answering, it would make reading it ALOT easier (e.g 1. It works fine) Now onto the questions: 1. How does spot pass and streetpass work? Will people with australian 3DS's be able to communicate with my American 3DS? SOME WHAT ANSWERED 2. Can I play online games with people in australia, e.g My friend came over and we wanted to have a game of mario, he had a australian 3DS and mario kart game could we still play together 3. Can I play with other people around the world e.g say I'm lying in my bed and I want to join a random mario kart 7 game with a few random people online would that work? 4. Do pokemon events work? e.g A new pokemon event for X, Y came out and I have my American 3DS could I just go to some australian game store/toys r us and I would be able redeem the item/pokemon. 5. Would DS games and GBA games work on the 3DS? ANSWERED 6. How would using an r4 chip work? Would I need a specific r4 chip for a specific region and must I download a specific version of a rom so the 3ds recognises it as a american game? SOMEWHAT ANSWERED 7. With an r4 chip can you play multiplayer? e.g could I have a pokemon battle with some random stranger that has a legit copy of the game? ANSWERED 9. Do you need a specific action replay device so it can be used on an american 3ds? ANSWERED Thanks in advance.
