Hacking protected savegames (wifi games) migrating to different wii

[y3468]

I have pulled all of the keys i need into FE100 Keygrabber (nand.bin) and I am able to pack/unpack savegame bins with no problems...But, there are a few games that still reject the repacked games (guitar hero 3 for instance)...from what I have learned, the game validates the savegame against the wii internal keys to make sure that the savegames can't migrate to different wii consoles. I am running bootmii and use savegame manager gx to install the savegames.

Anyone know what is wrong with what i'm doing? Do i need to pull a savegame of that title off my wii and just trade the guts of the savegames off of wiisave to get it to work?

thanks

I think it's the console ID where it compare from, not the keys.

but even the console id (NG-id) is included in the keygrabber...is there a reason why the repacked savegame for guitar hero 3 would reject the repackaged savegame?

If you just use Savegame Manager GX for the entire process, it might work.

On a side note, using StartPatch to enable copying of ALL game saves from the Sytem Menu even lets you copy Wi-Fi saves. I copied my SSBB save to my SD Card, to Dolphin to import the SAVE.BIN, and Dolphin worked on SSBB with the new save just fine. And no, I DID NOT have a NAND installed into Dolphin.

So, I'm pretty sure you're just doing it wrong, and that it IS possible.

Im not 100% sure if this will work but if you have priiloader installed there is a hack to remove the save copy protection then you can try copy it over your SD card then to another console

let me know it this works

all those ng-key, md5-blanker, ng-key-id, and whatever other magical crypto binary data that save packers use is solely for the system menu's amusement. saves are encrypted and signed with this data when converting to a data.bin. the system menu decrypts the data.bin, splits it back into individual files, checks the signature, and writes the raw files to the nand. you can use the magical crypto data from any 1 wii to build a a save and the save should install identically in any other wii. the content of the files will be identical.

to do what you are wanting to do, you will need to patch the raw files before you even start to think about packing it back up into a data.bin.



also, there is no specific format for the raw files that make up wii save data. it is designed by the game makers. every game is different. there can never be any program that can perform any (useful) action on all saves. you cant make a program that can region-change all saves. you cant make a program that can patch any, and all saves for a different friend code. this has to be done on a game-by-game basis.

It will

I don't know about StartPatch (I really don't like that app because you can't just enable/disable hacks, and they come in steps), but the Priiloader hacks don't work if you want to copy them back.
