How to Graph Calculator Emulators for DS

Although no officially released graphing calculator software is available for the Nintendo DS, the hobbyist programming community has created several applications that allow you to emulate the functions of a graphing calculator. These programs are free to use, but you must have a DS flash cartridge and a MicroSD card -- these allow the Nintendo DS to run software created by the homebrew community.

Things You'll Need

MicroSD card
MicroSD card adapter
SD card reader
Nintendo DS flash cartridge, such as the AceKard, M3i or R4i
