Homebrew Would a Ninjhax-based PK6 (edited Pokemon) importer be possible?

[flarn2006]

I personally wouldn't have any need for this because I use Gateway, but I'm assuming things like Pokemon Link (OR/AS demo uses it to transfer Pokemon to the full game, for instance) would use extdata. If this is the case, wouldn't a 3DSX homebrew be able to write to this, letting people import hacked Pokemon using nothing but Ninjhax?

EDIT: As I mentioned in my last post here, there's now a much better way to do this, so this thread is now irrelevant.

That I understand, Gateway pseudo-encrypts, or uses an old encryption that's decipherable . A full retail game likely would not have its save be modifiable. You would need the Nintendo Dev tools to take a crack at it, and those only run in Gateway mode--which, well, requires a gateway.

Furthermore, retail games only run in retail classic mode, so correct me if I'm wrong, even with a Gateway, you can't load the dev tools to modify its save.

Does it actually stores the data in extdata? If it just plainly put the data there and have very simple checks (like hash, which can be recalculated) then it should be possible. Ninjhax can access all extdata it seems.

This could be awesome

I'm not asking about Gateway; I'm asking about Ninjhax. I already know it's possible with Gateway, at least if you're playing on a dumped (or downloaded) ROM, as I've done it myself. You just need to use SaveDataFiler to export/import decrypted saves, and PKHeX (on the computer) to edit them.

SaveDataFiler only works on ROMs because Gateway doesn't correctly decrypt OR/AS/X/Y saves. But i do think that Pokemon Link data is stored on the extData location, so this should be possible. THOUSAND WAVES/ARROWS ZYGARDE

I was trying to attack all possible scenarioes, and well, all of them stay in the as Gateway only options. There's nothing else. My post is a roundabout way of saying "no" it isn't possible. By you saying no Gateway, you're implying eShop or retail cartridge to the best of my knowledge. You can't be implying any sort of pirated CIA because you would need a CIA installer, which isn't possible without a Gateway or other flash cart that runs in unsigned mode.

Just did some research. it seems battle videos are stored on extData. But i dont know what else. in the 0000055d folder.

From what I understand, Regionthree works by taking over a suspended process (download play) to obtain its permission to launch titles. I see no obvious reason why it wouldn't be possible to take over a suspended game, and obtain permissions to read/write its savedata.

Figuring out the details would be tricky though.

hey, i like that. could be a way to run trainers/cheat apps in general perhaps?

I wasn't referring to regular save data. I was referring to "Pokemon Link", which other applications (like the OR/AS demo and Pokemon Bank) use to basically put items and Pokemon in "storage" in a way where the next time you start up the game, you can "claim" it from the menu. I've never used it myself, but since the data is accessible to multiple applications, I assume it uses extdata. And Ninjhax homebrew does have the access needed to read/write extdata, so if I'm correct it would be possible to create a 3DSX that loads a .PK6 file from the SD card, and imports it into the Pokemon Link data, so then you could open up a Pokemon game, choose Pokemon Link from the menu, and get whatever Pokemon you want. If this is possible, one could also program it to let you edit the Pokemon data right on the 3DS, so you don't need to be near a computer. (You'd obviously need to be near your 3DS, which is technically a computer, but you know what I mean.)

I acualy was wanting to make a simple sav file editor for pokemon as a 3ds homebrew. But i dont want to start anyrhing untill i can get a gateway so i can properly test/debug the application

 

[mastermodr94]

Well the simplest way to figure out if the pokemon are stored in exdata is to make a dump then use something like the oras demo and pokemon link and then make a second dump. If the pokemon are stored in exdata then the checksums of the files should be different.

I like that, but one step at a time. Lets try and do the PK6 importer tool BEFORE we try to make a 3DS-based PK6 editor xD

This should be possible with MrCheeze's extdata tools as long as we recalculate the checksums and such.

The quickest way to find where Pokemon Link data is stored is to run Pokebank. Stored Pokemon accumulate "interest" in the form of PokeMiles or Battle Points, these points are then imported to your main game via Pokemon Link.

I like where this thread is going

 

[flarn2006]

I'm currently re-downloading the OR/AS demo, which lets you catch a Pokemon and send it to the main game via Pokemon Link. I'm gonna play through it real quick, catch something and name it, dump all my extdata, and search for the name. That should show me where in extdata it is, if it does use extdata.

I'd use Pokemon Bank so I don't have to play through the demo, but that costs money, and SaveDataFiler provides the same functionality in a much better way. (It's free, the files are in my control rather than Nintendo's, and I can make whatever edits to it I want because it's my data.) Definitely not about to pay for Bank.

Make sure to make a bacup of your exdata before and after to see if it is even stored there

I plan to. Is extdata the same thing as "Extra Data" in Data Management? Because if so, there's something listed there just called "Pokemon" that doesn't list any specific game, which looks promising.

Probably.
You need to know the extdata id though.
