XP is a complete operating system, not simply an operating environment.
There are a couple of places you can buy R4 for the Nintendo DS system. You can buy this at Best Buy or GameStop.
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
to put chetas onto your r4 you first must download the cheats or buy an action replay card to use the cheats you downloaded you put them in your r4 system folder and make sure it is a dat file
The R4 card is pretty simple. It works using a memory chip (usually a microSD) you simply hook the memory chip (not the r4 card) into a computer, download the appropriate files for your R4 card (the R4 Kernal) at http://www.r4ds.com/ . Then from there all files can be dragged a dropped onto the card (using your basic operating system's explorer [Things like my docs]) I recommend creating a music and games directory though, for simplicity, also, don't forget that the r4 card can hold and play movies, as long as the appropriate player and codecs are there. You just unzip the patch, and copy the music files into the root directory of the MicroSD card, then they can be played.
