1. No it can't be played on the DS, 3DS games are only played on a 3DS system while DS games can be played on both the DS and the 3DS system. 2. Yes the 3ds is region locked, you have to get an australian version of the game.
Can I play my 3ds games on my PsP? What about my macbook pro, or pc, or my ps3, xbox, or wii, or ipad, or iphone, or ipod, or gameboy advance, can I stick the game cartridge in the dishwasher and have it play? It just seems like all by electronic devices should be able to play my newly released nintendo 3ds games.....
People are still confused by the name, thinking a 3DS is just a 3D version of the regular DS. This is further complicated by the fact a 3DS can play DS games. While the name seems fittingly perfect, Nintendo should have realized that after the DS, DS Lite, DSi, and DSi XL, non-gamers would just assume the 3DS was another DS upgrade.
Who cares. None of this is rocket science. If this many people still cannot figure out the difference between this generation and the last, I might as well hang myself in the basement to save myself the grief of having to interact with these people.
And it's ok to cheat, google isn't hard to use unless you're retarded. Survey says if you can figure out how to post a topic on amazon, you know how to look something up on google.
Some of us have never played a DS! We are just hoping to make a kid happy on Christmas morning. Maybe you should just take it easy, be nice!! You need to get a life so you don't get worked up over a simple question.
No need to look down on people who are not game-savvy. Just today when I was shopping in the electronics section of a local retail store, some parents asked the retail clerk if their son would be able to play Mario Kart 7 on his regular DS. The clerk said he wasn't 100% sure, but he thought it could still be played in 2D mode. While I usually mind my own business, I kindly interjected and explained it could not be.
Wow, a lot of rude people on this thread. It has the name DS in it, so they probably were wondering if it would work in the older systems without the 3D effect. I don't think it was a dumb question, and not worth getting upset over. Has anyone tried to cut the plastic tab off, and put a 3DS game into a regular DS? Seriously though, Nintendo could have made this work in old systems if they wanted to, but they want to move people to the new platform.
The reason that many of the forum regulars are getting annoyed with this question is because so many people ask it. There has been at least 15 threads throughout Amazon's site asking that same question since the 3DS came out. I'm not blaming any of these people, since it is their first time asking the question, I'm just explaining the situation here.
