Homebrew Is it impossible to backup and restore activity registry data?

[nicklessguy]

Sorry if it have been asked before. Search didnt give me anything.
Like title says, isnt there a way to get my log back from my previous sysnand backup?

Only if you back up the whole "Nintendo 3DS" folder.

I had my previous Nintendo 3DS folder on SD, but the formatted nand after arm9 setup cant read it. I still have my old folder stored, is there a way to make the system recognize it?

 

[3than_H]

Restore the sysnand backup using decrypt9wip

 

[nicklessguy]

But that will remove the arm9 exploit, wont it?

 

[3than_H]

i didn't think of that so idk what to do.

 

[nicklessguy]

Well, thanks anyway. I guess i will jusy have to say goodbye to my launchday long registry then... Oh well

Create an emuNAND on another SD card and use Decrypt9 to restore your backup to that emuNAND.

That might let you extract the Activity Log data like this (it's not easy, though):

JK Save Manager allows you to extract and transfer a lot more things than previous programs did--it is now possible to transfer Streetpass Mii Plaza progress without manually decrypting or dumping anything.

So we just need to figure out which saved data you need to dump in order to transfer Activity Log. Then create an EmuNAND on a new card, restore the SysNAND backup to it, and use JK Save Manager to dump it.

The problem is that nobody seems to know exactly what to dump. Someone already tried Activity Log near the end of that thread. F000000B includes icons for the software library in Activity Log (and Mii Plaza), but there is something else necessary as well.

I haven't tried transferring between systems, but I know the Activity log uses system save data. Maybe the system save data + icon cache in f000000b?

The icon cache in there is certainly part of it, but it doesn't seem to be all that's required. http://gbatemp.net/threads/release-...-cia-save-manager.413143/page-31#post-6151201

Edit: Never mind, misread...

IIRC, the savegame for another system app called "PTM module" is also involved, it contains a log of steps and titles played:

Edit: If you delete the Activity Log save, the next time it is opened, it will be rebuilt from the PTM one. This can take a while and it will display a loading screen.
