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.

Get nds-bootstrap.ini from TWLoader.7z, and overwrite the one in "sdmc:/_nds/".

That worked thanks!

It's normal with the new version of bootstrap that MegamanZX get stucked on white screen?

I started a debug of whats wrong with NSMB here, but I just need one of you guys to help me...

Whoever here has a NSMB rom, please do the following steps and take a picture of what you see:

There is a hidden crash dump screen in the game, similar to screens seen in other DS games developed by Nintendo. To access the crash dump screen, first crash the game (the easiest way to do this is by removing the game card during gameplay), then hold L + R + A + Left, let go, hold Down + B, let go, and finally hold Start + Select.

^Man, i cannot even put NSMB on the roms folder of TWLoader, it freezes the program when analyzing the icons..

 

[NightScript]

BTW, for those of you who have a white screen on either SM64DS or Animal Crossing: Wild World, the steps work for there also...

 

[vander263]

^So we can dump any game of Nintendo with this? why not launch a debugger-version of the emulator for this?

Thanks WarioTails! I just updated my post on Github with the screenshots you gave me.

Yes.

Pokemon Mystery Dungeon Blue Rescue Team works with MaxCross Method, otherwise it says "Error reading data"
Loading times might be faster than before

 

[NightScript]

^So we can dump any game of Nintendo with this?

No.

This is a crash dump, and will only work with those 3 specific games.

why not launch a debugger-version of the emulator for this?

Because these crash dumps will tell you the error of nds-bootstrap. There is no way to test nds-bootstrap on a debug emulator.

And TWLoader's setting actually doesn't report crashes...

 

[WarioTails358]

Download play works on pre release bootstrap.
My old 3ds can connect to my new 3ds running ds download station on twloader and can download titles/movies and run them.

[Dracari]

Mystery Dungeon :Explorers of Sky is working but has a new Issue,
weird repeating error" Loop, but finally gets to Pokemon Questionnaire (attached a recording of what its sounding like. thsi starts after a CS fails to finish playing but loads to Press start screen and gets worse at the Questionnaire screens.)

 

[RocketRobz]

MegaMan Zero in MegaMan Zero Collection

Stage graphics are glitchy.

I updated the NDS bootstrap to the newest Beta release. Now everything just white screens when I load a game.

Try reinstalling the TWLoader TWLNAND side CIA, and setting VRAM boost on.

 

[NightScript]

Disable the ARM9_(something) lock!

Umihara Kawase DS and Bleach Dark Souls still white screen. Wasn't sure if this update was just speed improvements or could improve compatibility too so thought I'd share just in case.
