To start with locate the mini disc and insert it into your PC's cd/dvd tray, it

should auto open to view files, look for the folder;  system v 1.18,  open it and go

to; english, open it and there should be 4 system files.  locate the USB card reader

and slide the little tiny memory card into the end of it, make sure it is the

correct way up, then insert the reader into a USB slot on your PC, it should appear

on your PC as a  removable disc.

Return to the 4 system files from your mini disc, you now need to copy and paste

them into the removable disc (memory card) when this is complete take the memory

card out of the reader and insert it into the R4 device (again make sure it is the

right way up) insert the R4 device into your ds, as you would any normal ds game,

and then switch the DS on.

It should then automatically boot through to the R4 system menu, where you should see

3 icons appear on the bottom screen, 1, smiley face (game file)  2, musical note

(mp3 file) 3, square face (e-book). when the icons appear just turn the ds off, the

memory card is now ready to accept game roms.

Remove the memory stick from the R4 and re-insert it into your PC, open the folder

again and you should see 5 files (it creates its own menu file when you boot up the

DS) Remove the mini disc from your PC, as you should not need it again (unless you

delete the system files off the memory card), and put the DVD of games into your PC.

Open the games disc then each game you would like you will need to unzip/unpack the

actual game "Rom" (when unzipped it will appear as a "NDS  file") copy and paste

your selection straight onto the memory card (do not put into any folders just into

the card).

You will fit approx  40-45 games on the memory card at any one time, for a different

selection just open the card delete the game+save file you do not want (leave the

system files) then copy and paste your new selection. 

You do the same with mp3 files, just copy and paste, and word documents the same.

When you want to play a game you tap the smiley face icon and the list of games you

have put on the card appears on the top screen, scroll down the list, click on the

game, and press A, then off you go, its as easy as that!! 

Any more queries just email i will help as much as i can, good luck! regards Nick
