In 2017, is Nintendo Switch better to buy for playing 3ds ds games?

In 2017, which we should buy, the latest Nintendo Switch home console or the hanDheld gaming machine 3DS/3DS XL? I will compare them and give you reply here. Still now, the 3DS or 3DS XL or NEW 3DS device is a good choice for playing games, because you can save more money for getting R4 card or Sky3ds+ to play FREE Games on it.

Conclusion
Switch won’t replace the 3DS as the Nintendo emphasizes all the time.To my mind, the 3DS is obviously an entirely separate piece of gaming hardware over the Switch. This is because the 3DS is more geared towards kids in terms of its library, especially in Japan. The Switch by contrast is all about bringing people together around a console that would never have been previously available outside the home.

Nintendo Switch supports 3DS/DS games in 2017?

No, currently Nintendo Switch only supports a few games designed for it. It can not play either old NDS games or new 3DS games. But if you buy the 3DS console, you can play both NDS, 3DS, GBA, SNES, NES and other old classic games with game cartridge, homebrew exploit or flash cart.

Can Switched be hacked to play free games like Nintendo 3DS?


Whatever you know or not, the Nintendo 3DS is fully hacked by flash cart to support Free NDS and 3DS GAMES. Even the latest 3ds v11.3 firmware is cracked by R4i sdhc 3ds, Sky3ds+(you can get in R4SKY3DS.COM) and 3ds exploit to play pirated ds or 3ds roms or the third-party homebrews.

So what about the future of Nintendo NX or Switch, will it be hacked by a flash cartridge too? Maybe the hack for Nintendo Switch will be a thing one day, but at least in the following 1 to 2 years, we are too early to talk about it. After all, the Switch console is a totally new machine not based on any other Nintendo's product.
