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.

kinda weird why the pokemon distribution roms don't work yet still give same errors if you were to use it with the old bootstrap with no card read support they aren't even games and are small roms

A fair warning and note to all: If you don't wish to save, keep ALL cards out of SLOT-1. THE SAVES WILL BE OVERWRITTEN IF THE SAVE CHIP MATCHES.

For example, running MKDS with an AC:WW game in SLOT-1 will overwrite AC:WW's save, since the chip is the same.

However, if you wish to save like this, TWLSaveTool can tell you the chip type. Just backup the old save first.

Does that mean as long as we have a (different) nds game with the same save chip, we can save the game to that without needing a card of the game we're playing?

Yes, it does.

What game are you running?

 

[JCCG1989]

What game are you running?

yeah sorry for not including that, Megaman ZX

 

[RocketRobz]

yeah sorry for not including that, Megaman ZX

Make sure there's no Slot-1 card inserted.

 

[JCCG1989]

Found the error, I had Monster Hunter Generations cartdrifge in my slot 1, works now after retiring it.

 

[shutterbug2000]

Also, another warning: We patched out the card-remove checks. So, don't remove the SLOT-1 card at all, it has a huge risk of destroying the save data.

Do we still need to decrypt arm9.bin from the nds file?

 

[rikumax25!]

No

Do we still need to decrypt arm9.bin from the nds file?

 

[Deleted User]

Now... *Rubs Hands* What do I need to install?

Edit: Ah, I see it now

 

[shutterbug2000]

Do we still need to decrypt arm9.bin from the nds file?

No, that's done automatically now.

 

[PRAGMA]

No, that's done automatically now.

Sweet, If that was never accomplished I woulda worked on a Drag/Drop application that would insta do it too.

 

[JCCG1989]
