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.

after doing this, Kirby super star ultra still gives me a save error, saying unable to read data.
does it matter that I have a save file already created?

No.

 

[WarioTails358]

No.

I'm also using the USA version of Kirby Super Star Ultra.
Should I try a different region rom?

If you want megaman zx and advent working again, make sure you have the latest unofficial and add this to nds-bootstrap.ini
PATCH_MPU_REGION = 1
PATCH_MPU_SIZE = 3145728

 

[WarioTails358]

After updating the bootstrap to the latest unofficial one and changing these settings to
PATCH_MPU_REGION = 0
PATCH_MPU_SIZE = 0
No games load for me and
When I remove the = 0 or the text all together for these 2 options
My games load again and Kirby super star ultra still gives me a save error.
So now I don't really know what to do now.

Try formatting your SD card to FAT32 with 32kb clusters.

I'm in the same problem, but I haven't updated A9LH in a while (only Luma3ds) and I haven't set it so that it would still work even if I removed the MicroSD card...

I kinda got download play to work? My other 3ds finds mario kart but it wont go past the downloading part, has anyone else gotten past this or is this all it will do for now.

Just wanted to put this here:

Super Scribblenauts (USA) Doesn't Boot (White Screen), just tested it out now.

 

[Makore]

Kirby Canvas Curse (U) doesn't boot (White screen)

Just gave it a try myself, stuck on "Downloading data" part as well.

I didn't even know this was possible until just a few seconds ago xD
There's no data being transferred from one console to the other over wi-fi, if they can communicate it means data is being sent and received, I do wonder why it won't download tho.

32kb? Why not 64Kb? It can cause issues?

 

[sj33]

Sonic Rush Adventure and English of the Dead are both supposedly working, but on loading the games I get an error saying the data cannot be read and to turn off the machine.

Anybody know what could be causing this?

Maybe you have a DS game in the slot-1?
Try to remove the cart if it's the case.

PATCH_MPU_REGION = 1
PATCH_MPU_SIZE = 3145728

How did you get these values?
And for other games? Can we calculate they?

IDK about EOTD, but Rush Adventure DOES work with MKDS as a donor (IDK why it does not work for some), and Super Star Ultra does too. SRA does also work with the MCM patch too (IDK well about MCM patched KSSU, last time I tried with MCM patch it still gave error).

English of the dead needs the arm7 donor path, ive just beat two chapters so I know it works.

^Thanks for the MPU_SIZE and MPU_REGION configuration, running Megaman ZX perfectly , but if you don't mind, how did you find this specific configuration?

About donor... I wrote in config path to rom with Mario Kart, but no Sonic Rush, no Mario Kart himself got me error "Can't read data". What i do wrong? 0_j

Its from ahezards' github

I need 3 people to help me test something. I loaded up an altwfc patched mkds rom, and it connects. Online play might be possible with this, but i need 3 people to test with.
