OCDM stands for Online Course Database Manager​

Features*:

• import and export courses, both** 3DS and WiiU
• cryptofix saves (if the game marked your save as "corrupted")
  • Note: this will overwrite the LockoutID in your courses, not in the save file, so please be fair and don't reupload others' courses
• make/apply save snapshots (exports all files which are used in the save)
  • Note: please format your save data before restoring your save otherwise the game could mark your save as "corrupted", and this one is not cryptofixable
• browse SMMDB
  • download courses
  • discontinued

*: these features are in the latest build at the time of editing this post, so functionality in the public build could differ
**: due to differences in the 3DS and the WiiU version, importing a converted course file on a foreign platform could crash the game on loading the course

that is why I was wondering if someone had the complete save data file, so all the tools are avaliable

From what I found, you can't import saves to this game with likes of JKV Save Manager. Apparently it detects if there's other people's saves and deletes them from your system.

that is with extra data (courses), I thought save data was safe to transfer.

I have a save with all medals and course tools unlocked.

can you post the Progress file?

It's hashed. You can freely transfer extdata with a little modification tho.

So the regular save is hashed as well? That sucks.

Progress (save data) is hashed, courses (extdata) isn't.

Thanks for the clarification.

 

[Svaethier]

Still can't use other's ext data yet as the game just recreates empty ext data if you try.

What modification is that?

Thanks for the clarification.

NNO! Course files are *double*-hashed! They contain 2 checksums! 2! The master hash (first 4 bytes)'s algorythm still needs to be broken :/

It means save resigner is needed to resign the SMM saves? Is there workaround to get other people's save to work with different 3DS?

Are you sure the whole file is hashed? I could easily move them between 3DSes just by overwriting the LockoutID.

Not the whole file is hashed (it looks like the "master hash" isn't being affected by the 0x1C-big header at all), so that's why you can edit it, becase Ninty is a derp

Im a bit confused on something, need some clarification...
Whats the difference between a save file and exdata? is it possible to import someone else's save file but NOT created courses?

Im looking for a save file with all the tools unlocked. Im not looking for courses.

Is it possible? thanks for the help...

Well, I haven't tested it, but I don't see why it wouldn't work to just overwrite one of your courses with someone else's.
But otherwise ye, if you have modified the file(s) yourself, then you'd need to recalculate their hashes.

The savedata (named "Progress") stores your current progress (d'uh), unlocked stuff, layout information, LockoutID, and some other unknown stuff.
The ExtData contains all the courses. Only the courses.

Nice work man, if you ever need help, just ask me.

 

[Jackson Ferrell]

So does that mean I can download other courses from the internet straight onto the 3ds with this, or do I need a computer to download them then transfer to the SD Card? (Sorry if it's a useless question)

Once this is actually fully functional then you can but this barely works right now though. Only one function works right now.
