DSiWare on Wiimmfi

NintendoFan · 5. September 2015, 19:37

Is this possible? I'm trying to connect to Wiimmfi on Bomberman Blitz (I do this by setting my DNS settings to Wiimmfi's IP) but it gives me the internet error code, 20100.

And yes, I'm sure my internet is working fine. Otherwise I wouldn't be here right now, typing this post.

20100 is reported when the game uses SSL. Can you make a dump?

Maybe that game also needs a no-SSL-Patch like wii games.

NintendoFan · 5. September 2015, 20:23

Sorry, I can't because I don't know how to... And when I try, I don't know what packet has the attempted connection.

is it possible to transfer the DSiWare to the SD Card, patch the game file and put it back to the DSi?
I don't know much about this, because i never bought a DSiWare.

NintendoFan · 5. September 2015, 20:53

@ventord No, you can't do that on a DSi and I'm not sure on a 3DS but it automatically saves DSiWare to the system memory, not the SD card. Because of this, I'm sure you can't move it to the SD card. I haven't checked myself though.

Well... apparently is possible to do that on a 3DS.

Well I was wrong, but we don't know what format DSiWare games are in, and where it'll be copied to the SD card.

Billy549 · 5. September 2015, 22:52

DSiWare will be in APP files probably.
And yes we do know where it goes.
SD:/private/...

private/ds/app/title/ ....

And i think that the format is .bin but not sure.

EDIT: looking at this page, the DSiWare is saved on the SD card in .bin format along with one .lst file.

Billy549 · 5. September 2015, 23:23

Is it encrypted though?

Leseratte · 5. September 2015, 23:24

It is probably encrypted to stop you from copying it to another DSi system.

NintendoFan · 5. September 2015, 23:42

@PokemonAcer Yes, because when I open some of the game's files in a hex editor it just shows garbage data.

Maybe the compression is the same as DS & WiiWare games?

Edit: It isn't. I tried all of them (And by all of them I mean the ones that can be found here) and they all returned a "WARNING: File is not X compressed!"

Billy549 · 6. September 2015, 00:31

It's encrypted with it's own key. That's why you cant reset and put it back onto the DSi, and that's why it wipes the 3DS when you transfer it to another, it has to send the license over with the game.

NintendoFan · 6. September 2015, 07:50

Is setting the DNS settings even the correct way to do this? I honestly don't know.

Also, since 3DS homebrew is early in development, and as soon as we figure out how DSiWare games are encrypted and how the 3DS loads it, we should be able to make a patcher, right?

Billy549 · 6. September 2015, 11:55

3DS Homebrew can only load 3DS games, and ATM only because of region-unlock. We have no way of launching DSiWare or DS games IIRC.
Anyways, ^ is not perfect (you have to use a DNS to get to it) and it'd just be a big pile of homebrew that someone has to make.
I'll see what I can ask my friends about DS launching, and if it's possible, but it'd be really hard to decrypt.
Flipnote Hatena used HTTP and sudomemo already has *that* sorted.

NintendoFan · 7. September 2015, 19:54

Mario vs. Donkey Kong March of the Minis also gives 20100, so apparently this and Bomberman Blitz use SSL.

But I don't think the Mario game will work because you could upload levels to NWFC where people could download them, and IIRC the server for that isn't working properly.

Billy549 · 7. September 2015, 20:01

I've checked a lot, here's what I got:
- I can't decrypt DSiWare if it's gone to 3DS, so I have nothing to decrypt.
- I can't encrypt them either
So no, there's no way to do this.
We COULD try with an invalid cert on DS(i) because Nintendo might not've checked. Someone needs to find out.

Sepalani · 7. September 2015, 20:59

You can decrypt DSiWare, at least it's possible. Encrypt them back might not be necessary if emulators can execute them, even though I've heard that not all DSiWare were working properly on them.

Billy549 · 8. September 2015, 04:10

You can't decrypt it if you put it onto a 3DS.

Sepalani · 8. September 2015, 08:55

@NintendoFan
Have you tried the method used to decrypt/extrack/rebuild 3DS games? You need a softmodded 3DS though. What is the extension of the file you've ripped? You might find and answer if you google them.

NintendoFan · 9. September 2015, 03:14

@Sepalani I don't know how to decrypt 3DS games. And also, even though none of it is actually installed on my 3DS, I can run 3DS homebrews through Tubehax.

As for the game itself, it was in a .bin file. There were also some other game files in .pls and .ppm.

ventord · 9. September 2015, 22:38

I found this on the Wiimmfi stats page:

I'm confused. There's no DSiWare game support on Wiimmfi at the moment, so, why is this game on the page?

NintendoFan · 10. September 2015, 02:14

@ventord It seems, that there is a DS, WiiWare, and DSiWare version of Tetris Party Deluxe. And both the WiiWare and DSiWare version use the same ID for login.

NintendoFan · 5. Oktober 2015, 06:10

*revives thread*

Can someone figure out how DSiWare in encrypted?

Billy549 · 5. Oktober 2015, 16:41

It's encrypted to a point that we can't do it.
