Homebrew DS(i) Mode hacking progress thread

[Arubaro]

CBDS time?
I'm drooling

 

[Aurora Wright]

BTW I found the offsets for NAND read/write in TWL_FIRM, they're the exact same patterns as NATIVE_FIRM.
I also found the MPU offset and the offset where the emunand code gets copied to in NATIVE_FIRM by cfws. However, I couldn't find the SDMMC struct...
From this, I guess NAND -> SD redirection for TWL_FIRM is possible. If I found the SDMMC I would have attempted it myself (I'm not a reverse engineer).

Yay! Things are actually happening in here. It's good to be alive these days

Great!!! Hope I could help in this amazing project, but I'm stuck trying to compile with cmake, I'm such a noob

Compile what?

 

[Billy Acuña]

Compile what?

Well, with anything with a CMake List, there is something wrong with my dev enviroment.

I mean what are you trying to compile related to this thread?

None at the moment, but there is something.

How about region free DSiWare loading? I just got US Dark Void Zero to run from Home Menu on my EUR N3DS
The region flags in SRLs are the exact same as for 3DS titles

Oooooooooooooo...

 

[Apache Thunder]

Yeah. Just set all 4 bytes in the region code to FF and it will become region free. That works with the new sig patches.

 

[Zidapi]

It would be Nice if you Could run the Old DS/DS Lite Firmware on the 3DS. I love having Pictochat and even the Alarm Clock! Or, is there a way!? I have a R4S DHC 2014 Edition Card on me (W/a 32GB SDMC).

You're thinking of DSi, not DS(lite).

 

[Apache Thunder]

Pictochat from DSi does work on 3DS. (but it won't show up on home menu since it's set to a system app). I tried to edit the TID so it's not a system app and show up on home menu. It would show up with proper icon and everything but it crashes with "Error has occurred".

I can change the other bytes in the TID, but as soon as I change the byte that changes it's type...Boom crash.

Does the early patch help?

Well, just changing the first byte to "7F" does the trick
I had a look at an EU and an US SRL and the values are the exact same as described here: https://3dbrew.org/wiki/SMDH#Region_Lockout (0C for European games, 02 for US games, rest is zeroes).

Without the patch you couldn't even change DSiWare titles at all.

 

[pdapanda]

Have you guys heard of japanese Advance Wars Days of Ruin in dsiware format ?
I have it on my 3ds, but never able to decrypt the cia.

 

[hippy dave]

Is it weird that the first thing I want is that Lemmings homebrew?

 

[Zidapi]

@pdapanda posted this in another thread. Perhaps comparing the retail version to the DSi one will point us in the right direction.

there is one retail ds game released for jpn 3ds，Advance Wars Days of Ruin

however，nintendo never released retail version of japanese AWDOR， although it was contained in US version， finally they released the game in dsiware as redeem reward for club nintendo in 2013.

I think Advance Wars Days of Ruin dsiware use rip rom, the actural game size is 50.9 MB, if it makes sense.

What's a rip rom? (Unless he means the DSiWare version is simply the ripped rom of the DS version)

 

[TimX24968B]

I just want to clarify something: when you say DsiWare, which do you mean:
1. Dsi games? (are they different from ds games?)
2. Dsi homebrew?
3. Ds/Dsi system applications?
4. Ds games?
5. Ds homebrew?

and which ones would we be able to do anything with with a patch like this?
