How do I unzip a .nds file and a .war file before

make sure they are nds files. check time and date are right on ds

Mine works fine!!
Download English 1.18 from the R4 website.
Unzip
You should have 4 files on your card
_system_
moonshell
_DS_MENU_DAT
_DS_MSH_NDS
you then add the .nds game files from wherever you get them from
Make sure the card is formatted first, ie there are no other files on it. try FAT. rather than FAT 32. I can't remember which but I've had no problems with either the card or the software, best thing since sliced bread, and it only cost me a tenner.

download .nds files from web sites you can join some site some of the popular sites have been forced to close. you can still get them from bittorrent sites. when you download them they will be in .zip file just open your unzip programme and unzip the .nds file as this is the nds game file.

Download these things: DLDI patcher - http://gbatemp.net/index.php?download=81 NDS Backup Tool Wifi 0.31f - http://gbatemp.net/index.php?download=2719 Filezilla https://www.ohloh.net/projects/filezilla/download?filename=FileZilla_3.2.6_win32-setup.exe
--First time only--
Install Filezilla. Now unzip the DLDI patcher's ZIP into a new folder. Unzip the NDS Backup Tool ZIP into another folder. Open up the NDS_Backup_Tool_Wifi.ini file and change the IP address of the DS if necessary (if unsure, leave as is and change it to 192.168.1.10 or 192.168.2.10 if it doesn't work) Open up the DLDI patcher, drag and drop the NDS_Backup_Tool_Wifi.nds file onto the patcher and then select R4DS (Revolution for DS) from the drop-down menu. Then, copy over the NDS_Backup_Tool_Wifi.nds file and the NDS_Backup_Tool_Wifi.ini file to your R4's memory card (location doesn't matter).
--After doing the above--
Run the tool and follow its instructions. When you have followed its instructions and you need to get the game sent to your PC, open up Filezilla then type in the following: Server: 192.168.*.10 (whatever you chose) Port: 21 (default) Username: anonymous Connect, then look for your NDS file and save it to wherever you want. Wait for the transfer to complete, then close Filezilla and restart your DS with your R4 inside. Repeat for each game.

patch GTA using dslazy.

Small gui to some NDS utilities.

- get nds file info using ndstool.exe
- append a file to ndsloader.bin
- apply ndspatcher.exe to a nds
- grep for bricker code in .nds
- trim blank space out of a rom
- unpack and repack a nds using ndstool

extract to somewhere eg C:/ds/dslazy
run dslazy.exe
select a nds file(which is GTA right?) by hitting the "..." button.
get the rom info by clicking the [?]
hit the desired patch button
select where you want the new file to be if appropriate..

Unpack the said nds file(GTA)
search ARM7 download on Google, and DL it
then paste it on the unpack nds files which is on your ds lazy folder "NDS_UNPACK folder" overwrite if ask. Then repack it save the repack nds file wherever you want and your done copy the patch GTA on your SD card. If you don't get it try searching ARM7 patching on google.

Go to www.r4ds.com download & unzip the kernel. This will create a folder with the operating system.Copy these files to the root of the SD card (There should be 2 files & 2 folders) After this, copy the .nds files also onto the root of the SD card, and the games should be visible & playable when you turn on the DS 
NOTE: this will not work for the Nintendo DSi 

Hi,

I have several of these 'TT Cards' for my kids.

Firstly put the micro sd card in the sd card adapter and format it in your PC. When you go to format please slect restore default settings and then click format. (That is ofcourse if you have a micro sd card? If not a 2gb one will hold about 20 games)

Then open the location that you sd card is E: etc and create a new folder called Games. This is where all the .nds files you would have downloaded will be put.

You then need to drag and drop the latest firmware for the TT card onto the sd card in the PC. You can get i here:
http://www.neoflash.com/go/index.php?option=com_content&task=view&id=219&Itemid=27

Just download and unzip. If you need it winrar is a free download.

Ok, after you have done all of that you need to take the sd card out of the PC, put it into the tt card, put the tt card into the ds, turn on the DS and let it start up.

If all is done properly you should see a nice TT card menu on the screen!!!

Now turn off DS, remove tt card, take sd card out of tt card, place micro sd card into adapter and then into pc, open sd card location, open games folder and just drag and drop downloaded nds game files there.

Please remember only .nds files can be played on a flash cart of which a tt card is one.

Also look for a ds rom trimmer tool on google. Will make the game a lot smaller so you can get more on the card.

Hope this helps.

Anyproblems please message me back.

Best Wishes,

Karlos

first , download the firmware

http://gbatemp.net/index.php?download=2304

google for "nintendo ds roms"

unzip/unrar files and put them on card (should be .nds files , like "pokemon - diamond.nds")

this is what i did ,

put the micro memory card in the adapter and load it up on your pc's card reader,click to view folders and, create new folders on the memory card , games/music/pictures , now unzip the games you have got till you see .NDS . files,, then just copy and paste these in the games folder , you may think this looks messy with loads of games files ,but it sorts itself out ,..

You will need to buy a R4 card from here http://www.r4ds.co.uk/

you then download this software : http://www.utorrent.com/?client=utorrent1830 to enable you to download the software from the internet

then use this site to search for the games you want http://www.mininova.org/

once you have downloaded the game - copy them into the games directory on the R4 card
