Homebrew Nintendo DS games Injection?

I did find the tool that patches nds files to read from slot-2. It's called NDSPatcher v0.1.

the 3ds does not have slot 2 though

True, but that's why we could emulate a slot-2 in FCRAM like how AGB_FIRM does it. Instead of a GBA rom loaded there, an NDS rom gets loaded there instead.

how would you try to that to see if it works though

Spoiler

Try to swap DSi header with the DS one and play with the bytes and bit to see what happen. I can do that if you send me both roms.
Also, can you extract data from the DSi rom ?

It can't work, NDS use some special file like "arm9.bin "arm7.bin" and they work with the "header.bin"

So no DSi ware rom is not like DS rom

And what about DSi .nds roms, do they have arm9 and arm7 files in it ? If so, we could maybe "patch" them somehow...

There are different...

DS linker like the DSTwo can't run DSi ROM, if it was possible, we will can do this on the 3ds then...

thing is why don't people stop trying to hack dsi ware and try to do some thing with the twl so you can make it read data of sd card instead of game card slot

Modifying anything closed source is easier said than done. Not only would someone have to reverse engineer it, they'd have to write in libraries needed to address and support the SD card. It may sound simple to you, but that sounds like a nightmare to me.

so people hacked the 3ds and the firmwares closed source an theres rom hacks of games ther closed source

header.bin is new to me, but the other two... how large are they? and are they always the same size as i suspect? header is i think the interpeter, arm7 and 9 could be a dump of firmware of a handheld. dsi roms don't have the 2 bin files since that should be on the consoles side. could be wrong, i'm no coder... but i think i've seen those files somewhere... oh right i used them to accurate emulate nds roms... maybe these arm7 and 9 roms are the DSI version of what i used for NDS.

arm9.bin and arm7.bin size ?
depends on the game

 

[Deleted member 301661]

arm9.bin and arm7.bin size ?
depends on the game

wierd this depending on the game since i know these alike files we're used for Acurate NDS emulating, a dump of both processors/firmwares on board of the console (had a dumb of my own console used)... this shouldn't change by a game... have you tried to innerchange those files? cause if i'm correct it shouldn't be a problem.. the header is something i don't understand...

 

[hacksn5s4]

thing is dsiware could be put on the sd card on the dsi i think so woul it be possble to hack dsiware so you can install it to sd on 3ds

You can also put the dsiware on the sd card with the 3ds.... But it's unreadable on the sd card.

these file say how work the Game file system.
For example in mario kart ds you will see in the arm9.bin (example) "course1.bin"
If you swap these file, the game will cannot see which file to boot

 

[Deleted member 301661]

we don't know yet how to dump DSI games, just DS games were dumped, and since the DS games functioned perfectly on the DSI there was never the need to reinvent a dumper. reading from the SD-card wouldn't change the thing we can't inject anything yet since we don't have any DSI games, and these DSIware dumps don't accept DS roms to get injected!

then these bineries are code to the 2 the arm9 and arm7 processor i see, no than i don't understand enough of it. i thought it was like nintendo DS bios dump wich made sence to me since these bios dumps are commonly used it first stage emulators.

 

[MasterLel]

Let's say that ARM files are part of ExeFS, and the rom data is part of the RomFS
ARM files are like configurations files for the arm9/arm7 processors to run and properly handle the game I guess, and header is the information part.

So what if ->

1) We inject Pokémon Black RomFS instead of WW Touched RomFS
2),We take the DSi header of WW Touched and change it a bit to match Pokémon Black
3) We use Pokémon arm files
4) We patch the code.bin segments if needed

Then the game should work, no ? Of course it would require some work of reverse engineering and research...

well why doesn' some one try to reverse enginear slot 1 like get started on it it might take a long time but no ones even trying to hack it to get it to work

If it's something so easy, why don't you try? You seriously need to calm down, stop asking for DS ROMs without flashcarts, and contribute more.
