Which is the best 3DS XL Flashcart?

ARCADIA, Calif. - July 23, 2013 - PRLog -- Currently, the most recent 3ds system version is 6.1.0-11u/6.1.0-12e, except some outdated cards have been blocked, most of the major 3ds flash cart official websites have confirmed that their newest released card is working great with the newest 3ds software, including r4i gold 3ds rts card from r4ds team, supercard dstwo, r4i-sdhc 3ds rts, r4i sdhc dual core, r4i sdhc silver rts, r4i gold pro, ace3ds plus. But which is the best 3DS XL Flashcart? Does it support the latest/newest games on the 3DS XL? Games like the new super Mario and pokemon white 2 for example. Also, you might ask: I hear that no cards support the 3D function, but i  can always turn that button off? Here are some tips that will help you to choose the best 3ds xl card.

What are differences between r4 card and r4i gold card, bla bla bla?
R4i Gold 3DS RTS Card
At present, this card is generally considered as the best flashcart for Nintendo 3DS XL/3DS console. Here I meant this R4i Gold 3DS card http://www.thegamerdepot.com/buy-wood-r4i-gold-3ds-card-f... from r4ds official team. This card is widely popular, not only it is the most affordable card, but also it uses the great official Wood kernel team. Gets firmware updates quickly and regularly to let you play more new games, it allows you to play almost all ds model games such as super mario and pokemon. All the r4i gold 3ds rts cards from TheGamerDepot team comes pre-updated to work with the newest 3ds 6.1 system out of the box.
SuperCard Dstwo
Supercard dstwo is also a great card, it is more powerful than r4i gold 3ds card, it has extra features such as built in GBA/SNES emulators. But do note that the Supercard DSTwo's emulation is not perfect. There's still a lot of SNES/GBA (mainly SNES) games that don't run fullspeed. And it is a little bit expensive than the rest of the cards. If you dont need that extra features, I'd recommend r4i gold 3ds card instead, because it is hands down the most reputable card.
R4i-sdhc 3DS RTS
This is the newest version of r4i-sdhc 3ds card from r4i-sdhc team, it has amazing real time functions and gets firmware updates to bypass the 3ds system upgrade, other flashcarts might not be able to update themselves, making you buy a new one.
R4i Sdhc Dual Core and R4i Sdhc Silver Rts
Released by r4i sdhc team which is differ from the above r4i-sdhc team, but these two cards get firware updates pretty quickly and regularly, it might not be the most popular card, but both are very good cards.
Ace3ds Plus
The cheapest 3ds flash carts on the market, but if you aren't looking too much for features and want a flashcart with a stylish OS. This one is for you.

Can I play 3DS games on it?
First of all, there is no way to play 3DS roms on a 3DS with a flashcard at this moment. .The r4i gold 3ds card and other 3ds flashcarts are only able to run DS roms on your 3ds/ 3ds xl. You might have heard of Ace3ds pro. But actually it's not really a 3DS hack. It's just a DS pirate card with the PCB from a 3DS game also thrown in and you can switch between the two with a switch. And the gateway 3ds card, and the team claims it is the world's first working 3ds flash card, but it hasn't even been confirmed if it is real, and this cart is pretty restricted right now, one microSD per game, also it can not run normal DS roms, do not support system version higher than v4.5, not sure if it can be updated to work with the latest 3ds system in the future, and it's pricy.
