So this is a toturial for all the people who want to be able to play some ds games off of your sd card! So lets jump in!None of these applications belong to me!
What you need:

1)A 3ds with emunand or a9lh

2)fbi installed onto it

3)A computer with WinRAR found here http://www.rarlab.com/download.htm or some other thing like it


Steps:

1)Download the zip of the latest version found here
https://github.com/Robz8/TWLoader/releases and take the sd root folder and place everything in it on the root of your sd and then place the cia also on your sd

2)Find a nds game somewhere (It should be in .nds format) and place the .nds file into the nds folder (Make sure the game is supported here is the list! https://docs.google.com/spreadsheets/d/1M7MxYQzVhb4604esdvo57a7crSvbGzFIdotLW0bm0Co/edit#gid=0 or it may not work)

3)Then put your sd back into your 3ds

4)Open fbi and install twloader cia (it should be on the root of your sd unless you moved it!) then install twloader -twlnand side.cia it is in sdmc/_nds/twloader/cia

5)Go back to your homenu there should now be a present unwrap it and launch twloader cia

6)There should now be your ds game hurray!Remember the following! First of all there is no save support(Currently).If you have a actual cart of a game of the game you can save but it would save to the cart.

7-Zip is (in my view) superior to WinRAR and also free.

Ok I have added that in.

So if I have a cart that's the same chip type will it be able to load the save off it? Or just save to it?

TC4Shell is (in my view) superior to 7-Zip and also free, also integrated directly into Windows Explorer.

i put everything on root of my sd
i put MegaMan ZX.nds on nds folder
i opened TWLoader recently installed
opened MegaMan ZX on TWLoader
failed to read save data... what can i do?

 

[PRAGMA]

I installed Forwarder:
Put the _nds folder into sd root;
replaced the -dldi.nds with the one from this thread;
put warioware touched .nds into _nds;
installed TWLoader Side CIA;
Opened Forwarder
Whitescreen after DSi Logo and I can press the home menu button...
What am I doing wrong?
Waiting here on it for like 3-4 mins.

OK looks like twl launcher now supports sd games without using the patch.I will fix the guide!

Nothing until save redirect is added. You could use an actual ds cartridge that has the same save chip as the game your playing, and it will save to that cartridge.

So basically you can pirate Mario 64 on the 3ds without a r4card.

What if you have anoughter version of twloader installed and you want to upgrade to this one? Can you just simply uninstall it and then install this one even with anoughter twlnand side.cia already installed?

Not that game yet but the supported games yes (the list will get bigger).
I think you can do that or you can just use the file here and replace the file that was stored on your sd http://gbatemp.net/threads/nds-bootstrap-loader-run-commercial-nds-backups-from-an-sd-card.454323/

Is it normal to see that "an error has occured" screen while trying to load a game?(in this case, Mario Party DS, both US and EUR version)
I did install that TWLoader - twlnand side cia file aswell, but after trying the application for the first time.

 

[LuxerWap]

Wait, is it 1.6.0b the version we need to download? Cause the .CIA file to install TWL wasn't in the folder.

Make sure it is supported and double check to make sure that you installed 2 cias twloader cia and twloader side cia.

Yes you want the latest that is not 2.0 it should be in the root of the 7zip folder you downloaded.

Make sure you installed the TWLNAND side CIA to both SysNAND and EmuNAND.
