How to get things running？
A Nintendo DS (Lite)(must be needed)
M3DS Real Adapter
A micro-sd card (any will do)
A computer
A T-Flash / Micro-sd card reader (USB will do)
A Nintendo DS is quite obvious needed. Next thing we need is a M3DS Real Adapter (you can get any other type of adapter).
The micro-sd card is required to put your files on; this card is not included in the M3DS Real package. You can buy a 4GB micro-sd card, they are not very expensive.
If you didn’t get the M3DS Real 
package with a T-Flash card reader you should buy one. There are many different options, a simple all-in-one USB device is cheap and works perfectly.
The next step is getting some files installed on your micro-sd card so the M3 Adapter will work.
