Hi all, I am a IT student and I am currently trying to reverse engineer the inner working of the Gen IV Distribution ROM. I already figured out the basics but... Right now, I am facing an issue with the way data is encrypted. I already know of tools such as WC4PCD or PokeGen, PokeHex... but I am trying to understand and create my own program to decrypt and reencrypt all by myself. So I am asking if any one here as any leads or straight up know what encryption algorithm is used. I obviously did some research but no luck yet. (Chat GPT told me to XOR the file but idk what key to use). Thanks in advance, and my apologies if I made any english mistake

http://wiibrew.org/wiki/GEMS_Wifi Why I can't make it: I wish I could code these things myself, but I'm not really much of a programmer myself and don't know how to use DevKitPro or any good at C++ for compiling homebrew apps. Also, I don't own any compatible Wireless devices (RT2500~60 Chipset) with for capturing things like DS and Wii Signals other than the devices their selves. What it would do (More to come): A Homebrew Application strictly for sending Generation IV & V (Even though there isn't anything yet, It'll probably be fairly easy to dump them from Saves with Hex Editor just like I've done for HG/SS before programs were able to do it for you in Saves. Generation V should and will have WCs like GIV despite opinions) Wonder Cards wirelessly to the DS through *.pcd files. Having a Folder and selecting which Wonder Card you want to Distribute. Things to be added later: Wonder Card Picture Previewer (like Pokémon Mystery Gift Editor and it's Show Card Preview feature) [Vertical and Horizontal for 16:9 and 4:3 TVs] Cry Sounds when in Distribution Mode PKMN Sprite (Could have detection for Wonder Card Distribution Value, if Platinum shared, Platinum Sprite and so forth. Maybe a Box above the Wonder Card display) Throbber (Could have the PKMN Sprite Animate once sending the Wonder Card, or a simple square throbber) Settings to restrict Wonder Card's Distribution Value for each Game Version (Distributions for certain versions / All Versions) Wonder Card Queuer (Press a button to move onto the next Wonder Card in a folder, or select which Cards to Distribute, and hit a button to move on to the next queued Wonder Card) Wonder Card Capture Mode (Capture a Wonder Card that's in hosting mode and saves it as a PCD file) [Thanks to trance for the idea!] Concept Layouts (Might change the BG to a Darker Blue Tiled one for less eye strain): [Wii] Before Distributing (Press A to Distribute w/Animate and Sound Cry): [DS](Animated GIF) Before Distributing (Press R for Card Switch, A to Distribute w/Animate and Sound Cry on Card): How it would be useful: Anything you could think of really. Not having a Flash Cart but a Homebrew Channel on the Wii with a Retail Copy and DS. I mainly use custom Distribution Roms with Patchers to send my Wonder Cards to my games. I'm quite tired of using these things even though it's basic as can be. Plus it would conserve space not having multiple files that are 8MB/1.5MB. Where as it would take up 856 Bytes times around how many files you have on your SD/microSD/microSDHC Card. Conclusion: In the end it's also just as legitimate (Legal, for people using that terminology) getting the Event as long as you had the Wonder Card straight from the Event. It's a steal, and as great as acquiring an Event legitimately like PBR Pikachu for instance. It's the perfect bargin and solution for people not wanting to fiddle around with their Networks for the GTS exploits, and want a generated Pokemon with a different Nature randomly. If developers didn't decide on it originally because of some single Event that was made up by a fan, then why not a Wii Version? It's not like anyone is going to take their Wii to an Event and distribute some derogatory thing. Besides, PP does have some programs that deal with Wonder Card files at least. Why not? If it hasn't been thought of before. This is something to keep in mind though. I have a contact that has knowledge of sending Wireless Signal activations through compiling his own custom applications to a few DS games of the Rockman (Megaman) Series of games. I'll ask him if nobody else knows much about Wonder Card signals. Either that or I'll purchase a PCI Card that has the Chipset itself eventually for reading the WC Signals and attempt to figure it all out on my own. Both ways will take a long time probably. Thanks for reading.

I thought i would just send a link for the michina arceus i got yesterday from eb games in australia so please enjoy http://www.mediafire.com/?ziwqmvi1mmz

Ive tried importing a wonder card into my HG .sav file but everytime I do that I always get this message: and so on.....Btw, both of the PCD and sav files were selected then dragged into the .exe The same problem occured when I was editing my Platinum sav.

Anyway to make a SS wondercard work in platinum? whenever I SR my Mew in SS it shows up as a hack in Legal, I assume this is in someway due to the language patches applied to my back up ROM(?) I was wondering if using the WC PCD in platinum would help but when I add it to my .sav the green dude doesn't show up at the pokemart any help appreciated

How come when I use the PCD option for the Pokesav (Platinum) it doesn't work properly for me. If I use the PGT mystery gift file, I get the pokemon from the delivery man in the Pokemart. But if I use the PCD wonder card file, It ends up that after I press L+R on my Action Replay, I do get the Wonder Card but it says that you have already received this gift! How do I fix this problem? So is it that the PCD Wonder Card Files only create the Wonder Card but not the pokemon?

See this page for details and a download. Post and comments, questions, bugs, ect here. I'm attaching the source for any who may be interested; ideally it can be reused in a real sav editor with a real GUI, but I'll leave it up to you to determine that. That said, I know the import part especially could be optimized, but I was overeager to push this out the door and have no plans to come back to it now. Have fun. ;P PCD Safe.rar
