Best Website to Buy MT-card and R4i Gold 3DS Deluxe

ARCADIA, Fla. - Jan. 12, 2014 - PRLog -- Recently, I brought my kid a 3DS XL, his old R4 card does not work, and I want to buy a new card for my kid, but at the very beginning, i donno what card should i get, the r4i gold 3ds, the r4i gold deluxe card or the MT-card? Which is the best? And will that card definitely work on the console?  I searched google and Youtube for a couple of hours, and finally got an R4i Gold 3DS Deluxe card from R4flashcart. These are my own personal reasons for getting an R4i Gold 3DS Deluxe Card instead of the other 3ds flashcart.

First of all, there are 4 main types of 3ds flashcarts on the market that allow you to play 3ds mode games,the r4i gold 3ds deluxe card, gateway 3ds card, 3ds link card and mt-card. Be warned, all the working 3ds flashcarts require system version from v4.1 to v4.5. So ff your 3ds system version is lower than V4.5 but higher than V4.1, you can choose r4i gold 3ds deluxe edition, and yeah, the MT card allows you to play multi-rom 3ds games with one MicroSD card, which the other 3ds flashcarts can not do. But the r4i gold deluxe card will be able to support multi-rom function in the coming v4.0 firmeare soon. And I personally recommend the r4i gold deluxe card, because it gets firmware update regularly.
If it is above version V4.5. I'd recommend this r4i gold 3ds rts card,currently, it is generally considered as the best 3ds/dsi/ds flashcart out there, and it runs the wood kernel which gets firmware updates every month. But this card allows you to play ds roms only.
