Hacking Backup DS retail saves with 3ds

[Ronhero]

I posted this in the DS forums and didn't get any response and thought I say something here.

I have some ds carts that I want to backup the saves to my r4 for my 3ds. Every guide I have found doesn't seem to work for the 3ds and was wondering if there is some kind of 3ds app that can do this similar to SDF

I also have a few r4 cards and a dstwo if it helps

Not that I know of, I use a DS Lite and my EZFlash 3-in-1 to dump my Games and save files.

I was thinking about buying r4 save dongle, would this allow me to convert to a save that an r4 card would use?

This is actually possible and it's pretty easy. Just rename wnand:/ to cardspi:/ and it'll dump a ds save (or 3ds).

4.5 only though.

I have a 4.5 o3ds, I am so glad there is a way I am going to try it now, thanks again!

Edit: @zoogie So I edited the source to match what you said in notepad but now am confused as how to compile this back to a laucher.dat

Well here you go. It's really crappy, but it's a thing and you can play with it. I can't even figure out how to check the save size so you have to look it up manually for the game and use the python script to inject it to the mset file (LOL). Oh yeah, and the write back doesn't even work

I haven't tested the 3ds save writeback and I really don't suggest trying it for either ds or 3ds. Hopefully someone comes along and does a better job of this. Have fun.

@Roxas75 Do you think this could be implemented into rxTools?

 

[Ronhero]

That be epic; but I rather have it as an ntr plug in so both n3ds and o3ds can profit

Does this work? Thx!

There's a nds homebrew called "NDS Backup tool Wifi" by Rudolph and it has worked flawlessly for backing up my retail catridges saves, it can send the saves, as the name implies, to your pc over wifi and also can restore them. IIRC, it can also backup the game. I used it with an NDS, but hopefully it will work ok with a 3DS compatible R4.

Thxz, but I don't have a DS flashcart.

Anyone test this 3DS app? Does it work? Thx!

No, I can assure you that the tool will NOT work on the 3ds. Once you remove the flashcard so you can insert the game card, the 3DS will refuse to read the new cartridge.

Nope, it seems the 3DS side of things handles the cartridge, even in DS/DSi mode.

There isn't a way to backup NDS saves from a retail cart on a 3DS with just software?

From NDS mode (with a NDS flashcart)? Not currently, and it will probably never be possible that way. Now, there's limited ways with 3DS homebrew, and as 3DS homebrew gets more support, better options will probably pop up in the future.

I posted a way just a few posts above. It doesn't seem to work with pokemon though.

Does anyone read posts anymore?

darklink replies with NDS flashcart solutions when 3DS is clearly in the thread title.

WhoAmI says the tool doesn't work on 3DS's but doesn't indicate which tool, while I the whole time my replies are either indicating or implying a 3DS software solution.

Finally, zoogie replies and supplies a flimsy answer.

The 3DS tool, does it work? I've only seen that it doesn't work with a certain title, this is a fairly simple question.

I was responding to that:

I must've accidentally quoted your post, for whatever reason:

:S It's what I get for only having 3 hours sleep -_-

Yeah, that's why I was hoping it would've been possible to port this: https://github.com/lavanoid/savegame-manager
