Hacking 3DS Hack: "We hacked it"

Large Scale overwrite?!
Were talking about a file with less than a MegaByte

Kilobytes and bytes

Kilobytes and bytes

To be more precise, the save files of 3DS games are very similar to DS ones,
considering their format and their sizes, the biggest save file I've seen for 3DS was 512KB.

I think this should be pinned for the moment.
And I thank the OP for bringing this up. Many of use wouldn't even know this.

Now that I think I might just try the idea of using an eshop game as a bootloader. I'll see what the rest of Team Rocket can come up with. Hopefully Mad Hatter knows a way.

Pokemon Black 2 is 512MB. That's the necessary amount of memory needed to create a partition for most operating systems. As said large scale overwrite. You would have to recode most of the game. Have you tried recoding a Pokemon game to look like a different Pokemon game? It takes weeks, especially for one man. A simple overwrite would be changing R4,#0x4 to R7, #0x6.

No man, you don't have to recode the game, and you can't recode an original catridge.
All you can do is mess with the save, and there are many exploits that use that.

I remember whan I had a PSP, there was a exploit using the GTA LCS,
you simply changed the save, start the game, load the save and bingo.

I just panic, what if Nintendo blocks it? I'm getting anxious here, I'll rather have the files INSIDE the system, it's simpler for me than flashcards, all you need is patience.

Nope, you also need a bit of gambling spirit, as you can brick your 3DS (which is an inherent risk in EVERYTHING that messes with firmwares). You might also need to jump hoops and do specific stuff at specific points, of which an error could set you back a bit or ruin everything. You can also say goodbye to eShop access, which may or may not be easy to re-implement. Nintendo will probably fight tooth and nail if a CFW comes anywhere near the eShop.

There's your issue. It's a PSP. Different coding. If you're going to use a game save from a cartridge game you're going to need to recode the game to use it as a bootloader. The wii homebrew channel ran as an app, not a game. Problem with trying to do that for the 3DS is the cartridge boots from the cartridge, not the game save on the SD. An eshop game save would be your only choice. The 3DS has 128MB of ram. If you're going to run it off the cartridge somehow you're going to have a crappy homebrew. Easier to run off an SD. More space and you're using the SD as the bootloader so the ram and memory isn't used as much.

You still don't get it.
This case is very similar to PSP one, the only thing you need to change is the save.

The very first Wii hack used Zelda Twillight Princess game

You obviously don't understand. PSP, different coding. You fail to understand that disc games boot their saves from either a memory card or from their system memory. Neither of which the 3DS does. The wii hack used the Twilight Princess game save as a foundation for memory. It didn't use the actual game. I'll put this simply. The PSP and Wii do not boot their game save from the actual game itself. The 3DS cartridge boots the game save from itself. If you were to extract it you would still need to recode the game because it boots using itself in turn requiring you to recode certain parts of the game. What part of this do you not understand?

Let's put this simple:

1st: You can't recode a game from a original catridge, it's not rewritable

2nd: Where the save is do not matter for the case

3rd: PSP hacks like Lumines exploit, GTA LCS exploit and
Zelda Twillight Princess exploit used this same concept

4th: The PSP, and Wii scheme are using
an unchanged game, and a hacked save that works as a exploit.
Once you load the save on the unchanged game, it will run the exploit and bingo, it's done.

Damn man, I need to sleep

You clearly don't know what you're talking about. Cartridge games boot themselves. The Wii/PSP boot from an external memory source or system memory. Where the save is does matter. If you had half the education most romhackers you would know that. Let's say your argument that modifying the cartridge game save would work. How do you plan on booting it through the sd? Precisely, it can't and won't. The wii homebrew channel had its game save on the system memory/external memory. That is what it boots from. Do you know what the difference is? Quite simple really. It means it can actually boot the modified save. The 3DS cannot. Learn what you're talking about before trying argue.

vmm is right dr pikachu...

 

[Dr Pikachu]

vmm is right dr pikachu...

Actually he isn't. You can't run what you can't boot.

 

[pro2oman]

the cartrage has 2 chips the game and save....change the save doen need changing the game...its the same as wii reeding save of internal flash...
wii - disk and flash
3ds - rom and save men

save is an different part and not a part of the rom itself

Cant wait playing 3DS roms, hope it's ture

I actually happen to have taken the cartridge apart. There are three chips actually.

 

[pro2oman]

you can boot the game.. and you can never change the romitself on a original cart...its a rom.. read only memory...
to save you need to write... therefor its a different chip...clearly you don't understand this

No need to pirate.
We here on GBATemp don't condone in piracy.
