Homebrew DS(i) Mode hacking progress thread

[Aurora Wright]

Yo, just confirmed that my prepatched TWL_FIRM FIRM binary works with rxTools. I stripped out the "Magic" FIRM header from the patched FIRM file and placed that in rxTools/data folder replacing the existing one. My modified BlackJack DSi game even shows up on the home menu now. (in CakesFW with prepatched TWL_FIRM installed directly to sysnand, it wouldn't show up. One would have to boot it from devmenu) Curious as to why rxTools allows Home Menu to show it. None then less, it boots teh game despite the sig broken SRL. So it can work from rxTools. Someone should as them to add it to their source code.

Maybe (just having a wild guess here) for region free to work, Rx patches the home menu function that makes things visible, and this indirectly also fixed altered TWL stuff?
If so, you could try Cakes and using Freemultipatcher to see if it makes the icon appear (I guess the patch would be the same)

 

[Apache Thunder]

That could be it. I don't even recall if the particular game I patched was native to my region or not....

But the banner SHA1 HMAC is broken so even though rxTools gets it to show up, it's just a white icon. It boots though.

I checked and TWLNandFIler and WMTestTool both use FF FF FF FF in the region code bytes in the DSI Extended Header. I assume that makes DSiWare region free effectively. Might try to add that and see if they show up in CakesFW.

Does it have a negative effect with the rxtools's regionfree patcher?

 

[Apache Thunder]

Why would it? TWL_FIRM is patched seperately from NATIVE_FIRM. CTR mode stuff shouldn't be affected to changes in how it patches TWL_FIRM.

 

[Fatalanus]

So Apache Thunder, you with SteveIce and TuxSH managed to get DSiWare applications to load? Do you think that it could bring to an exploitation of DS backup at the end?
If yes, it'll be hard?

Good job, guys!!

 

[Xenon Hacks]

Oh boy I can't wait I can almost taste that chrono trigger run, GJ to everyone who is working on this.

 

[SLiV3R]

Very great work Apache Thunder! Hope it will work on Pasta cfw one day

 

[Aurora Wright]

I have succeeded in decrypting, patching and reencrypting the N3DS TWL_FIRM (fully, for the arm9bin I just had to make a couple changes to reinand) however I'm not sure how to rebuild a proper exeFS for the NCCH in the .cia (as the FIRM is in a ".firm" section which makerom doesn't support (?).
@Apache Thunder how can this be done?
EDIT: nevermind, did it manually.

 

[Stecker8]

after some investigation I was half wrong, you can use play european 5 gen pokemon games on american 3DS without problem but if you try to do the same with an american DSi doesn't work. I assumed that worked the same on DSi but I was wrong.

TL;DR 3DS bypass DSi carts region locking.

Dsi carts has got region locking?

Yup, DSi carts and later DS carts have region locking on the DSi, but apparently not on the 3DS.

So rxTools will be the way to go for DS(i) mode?

Apache Thunder mentioned it's also possible on CakesFW, and Aurora's working on it with reiNAND.

We're talking about the DS(i) homebrew right... What about .nds ROMs?

Way too complicated (because these games are designed to be run on a cart). Nothing in the near future at the very least, forget about it.

 

[Dr.Hacknik]

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 R4SDHC 2014 Edition Card on me (W/a 32GB SDMC).

 

[Aurora Wright]

It worked! I tested it by reinstalling the latest DS Card Whitelist on both emu and sysnand, and the patched N3DS TWL_FIRM to emunand, and the GW blue card works from emunand!

Are you going to share the files?

 

[Mrrraou]

Are you going to share the files?

I guess no one will share this publicly, as this is still copyrighted.

I obviously didn't mean it on here, I meant if she can upload it on that iso site.

 

[TuxSH]

The patches themselves are already public.
I'm trying to put them in rxTools.
