Nintendo Dsi

Hi my niece recently got a nintendo dsi and I found Vortex Ds program here that can download many games but I don’t know how to play them from an Sdcard. I googled and found quite a few methods and techniques was wondering which is the best way to play these games from Vortex Ds on a normal Sdcard and if it is possible?
I googled and found out about another type of card but yet still I saw a method using a normal card so I am a bit confused please help.
Thank You!
Answer #1
What you need to do is, look for something called an R4 or R4i card. They are a DS cartridge with a micro SD slot on them. You put all you games on the micro SD, put them in the R4 and then you just stick it in your DS and you have as many games as you can play.
Resource: I have personally done this

The best two cards are the supercard dstwo and the r4igold 3ds they are the only ones that can break the latest firmware i use the r4 one here’s a link for that card and the seller i usehttp://r4town.com/products/R4i-Gold-3DS-card-from-r4ids.cn.html
You will require a micro sd card to put into the flashcart 4 or 8 gb would be fine,then a small kernel has to be put on the micro sd heres a link for that http://www.acekardbuy.com/download/Wood_R4iGold_V1.56_r4idscn.rar extract it and open the folder you should see another folder named rpg and a data file these go on to the micro sd card as well as the roms you have downloaded.
