==Installation==
==Installation==
DSx86 does not have an inbuilt command interpreter (or shell), so you need to download a DOS program that provides the command shell features. Currently the only supported shell is [http://dsx86.patrickaalto.com/DSdown.html 4DOS version 7.50], freeware by Rex Conn & JP Software. The only file you absolutely need is the 4DOS.COM program, but if you have space on your SD card you can download the auxiliary files as well.
