nds-bootstrap:

Thanks to the work of ahezard, Gericom, Apache, Robz8, _catcatcat, and shutterbug2000 and other contributors, we can now load NDS games from the SD card, without any flashcard/SLOT-1 card.

Don't expect high compatibility, but do expect many, many updates.

How long will you make these people wait before you realize that DS emulation on the 3DS isn't feasible? Better options exist. This is why no one is pursuing DS emulation on the Vita; Drastic and Flashcarts allow you to emulate DS games perfectly, and the former option can be pirated.

Impetious Git, and get it thru this isnt Emulation, ist re-implentating the Functionality. , teh devs haveto reverse enegineer the Slot-1 Read/Write/SaveWrite/Save Read Protocalls and write em from scratch , they dont have the luxury of the NDS SDK. or Documented Code about this, and the devs are doing this "Because they can" Not to serve Whelps like you.

...let me put this in simple words...
THIS
IS
NOT
EMULATION

...this: https://gbatemp.net/threads/wip-3desmume-ds-emulator-for-3ds.430223/ is a emulator of NDS for 3DS. This is just loading the games like they were NDS games somehow into the 3DS right from the SD card.
EDIT: BTW it seems also kinda funny that shutterbug also happened to be the creator of that too :v
Still I would rather expect this than the emulator, since I have a O3DS.

You sir are stupid. This isn't emulating DS games. This is running them natively. Even more natively then flashcarts. Natively > Emulating.

All good pal you tried

@Naked_Snake try seeing if @Apache Thunder may have some insight about this,. its a long shot! :/

Thanks for that I can't even run a DS Cart for some reason

I wish I could help, but I didn't HAVE that error, since I also had a similar issue with DS games, that they sent me to the sleep mode screen. After I installed the homebrew stuff that was fixed magically. In the other hand, your error screen and that apparently you tried the Plailect method to fix the DS games but doesn't work, I have no idea.

 

[Stack3r]

A future TWLoader update will fix this.

Does the new update with the twl updater work properly? Like does it download the latest commits unlike the beta updater?

It downloads a good latest working commit.

 

[Svaethier]

It downloads a good latest working commit.

The commit from the site you're using doesn't build latest commit from card branch though :/

Edit: Unofficial commit breaks games from OP post.
Rogue agent and Yoshi touch n go doesn't work with it.

here for the others, (i linked this to @TheArcadeStriker in PM)
Phoenix Wright:AA Loading a saveit made to its donor card (MegaMan Starforce 3 Black ace)


However, if you watch the whole length (its 6 mins long as thats long it takes to boot to TWLoader-> PWAA-> load Save-> see first screen_switch to donor game to show Saves, Save in that game-> load PWAA again to show its save is still there even after Black ace made changes. looks like for these games it only overwrites within Slot01 in Black ace. leaving Slot2 intact lettingf it be for the 3 PW games while maintaining a active save for BA,

and game Report:
Game Name: Apollo Justice - Ace Attourney (PW4)
Region: USA
Commit: Unoffical: 5a3dd97 (Card Branch) (cant be arsed to test Release, See status)
Status: Slow is an understatement. 6 mins to get to Capcom Logo with pink bottom screen, 30 seconds that bottom turns black, about another 7 mins to get to "New Game" with the top screen severe glitched out(black w/ random pixels about the top-middle) tapping New Game is instant though! but about 3 seconds to transition from a frozen screen to seeing Episode 1. taping on screen has No sound. currently waiting to see if it gets into the First Episode Intro. aftre 10 min wait after trying to start the first ep Black screen of Death :/so this early on Compatibility with the series Ends with Trials and Tribulations

The entitlement is strong with this one. 1. This is native rom loading, if/when it's perfected, it'll be nearly as good as running a flash cart. 2. If you have such a problem with it, no one is breaking your wrist and forcing you against your own will to use it.

No they don't. What they actually did was reverse engineer Max Overload (which patches NDS roms to run from Slot-2) and then rewrite/reimplement them so that they read from the SD slot rather than the GBA slot. If they had to reverse engineer the Slot-1 access code from scratch it would have taken much longer. Still much harder than just porting an emulator over.

Great work, cant wait for it to advance more and become a full fledged DS emulator on the 3ds!

It isn't an emulator. It's natively running roms from SD card.

@Naked_Snake you could try restoring an old NAND backup if you have one. i had the same problem and that fixed it for me.

Yeah but I'd have to reinstall everything I have installed since that backup and I think it was months ago lol I will give it a try later
