Homebrew What is the difference between a DSIware .nds and a DS game .nds?

[GalladeGuy]

Before you go and spread all of your hate in the comments because of all the n00bs asking about DS injection, at least read what I have to say.


So I understand that we can't install DS games to the home menu because they're different then DSIware. The thing I don't understand is what makes them so different. Is it some kind of special header? Or something else? And what was the deal about that WarioWare DS on 3DS VC thing?

 

[Nathan's Waifu]

Well, you can launch games with the DS(NTR) header under the home menu if it isn't blocked by the whitelist. The header is not the issue.

But DS games read from a cart, so it will just hang if made into a CIA, unless the cartridge of the same DS game is inserted.

--------------------- MERGED ---------------------------

The WarioWare Touched! and Advanced Wars CIAs were made into DSiWare by special tools by Nintendo

 

[CeeDee]

They have the same game files in them, mainly, but the actual code has been recompiled for DSi to run off the NAND, and won't run in most DS emulators.

Plus only so much can fit in the TWL_firm partition. For example only DP can fit because PT/HGSS/BW/BW2 are too big

 

[Supster131]

unless the cartridge of the same DS game is inserted.

That's partially correct.
When I tried launching DS cia games from my home menu, it would crash if no DS cart was inserted.
BUT!
If any DS cart was inserted, it would simply launch that game, not the game installed to the home menu.

 

[GalladeGuy]

What if we could somehow trick the home menu into thinking we have that DS card in the 3DS when we launch the CIA version? Would that be possible?

Due to some slot-1 shit amirite

Yeah, that slot-1 shit is what inspired Apache Thunder's TWL launcher, it's the same concept. Just with the game and all the copyrighted stuff removed from the code.

No it reads directly from Slot-1 so for example if I had a Diamond cartridge in my cart slot and launched a pokemon Pearl cia, it would launch Diamond from the cart (I think that's how it goes)

if someone with amazing coding skills were to try I bet they could do that, but then the issue of limited space still persists and you can only have like 1 ds game on your nand. At that point "whoo hoo yay ds games works" but what's the point when a flash card with a larger micro SD card can play many more games in comparison.

 

[Supster131]

Yup, on point.
Only real way to make this possible would be if Nintendo released DS games on the eShop.
Then we'd be able to do the same shit we did with GBA games.

So what if we installed a tiny "placeholder" DS game to NAND? Then we could install a CIA homebrew (to SD) that would tell the console that an nds file on the SD Card is in Slot-1, and then launch the "placeholder" DS game, thus launching the spoofed Slot-1. Its a pretty absurd idea, but you never know what will work.

You got the concept down, that's the idea we all have.
Good luck learning to code something to do that.

How would the placeholder DS game read from the spoofed Slot-1? How could it see and read from the spoofed one instead of just launching from the standard Slot-1?

What data would it read from? I think it would still crash.

Can´t we make a cia of a game maybe a r4 launcher(having an r4 inserted) to launch from the menu that actually say r4 and not another game just for fun?

IIRC @Apache Thunder did something like that. He mainly did it for flashcarts that never worked with the 3DS, though, so I doubt it'd work with, say, your R4i Gold cards that still work on 3DS.

Some people in this thread said that if you have Y DS game inserted and you boot a X DS game cia it will boot into Y game so we could make a homebrew that says
R4 and a custom icon that say r4 and maybe a nice banner that say that too and make it to cia insert the R4 and boot that cia into the R4

Yes, you could. Apache made a "TWL Slot 1 Launcher" and all that would need to be done is change the banner on that to an R4 banner.

They have released a DS game on the eShop, warioware: touched. It's available through My Nintendo, but no one has enough points for it yet. Even with doing all the missions and the 200 coin bonus for previously having club Nintendo I'm still around 4 weeks from having enough coins.
