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

Keeping the same file size for malware is trivial. Same date is more so.

I wouldn't put much thought into it, it's probably fine.

I used the version from TitleDB before I knew there was a malware version. It works fine for me, not sure what version it is though.

Oh, I removed the notice because it turns out I made a mistake when compiling the version with the malware, and the brick code never ever gets called because there is no code to call it So the brick version is totally harmless (I tested it, and it didn't brick, nor wiped my entire 3DS NAND).

Edit: it turns out I forgot to remove the notice all this time...

Wait so was the malware version intentional?

It's a long story...

But long story short, it was never meant to be released into the public, it was only made because I was angry at something stupid, and it (very obviously) ended up backfiring towards me. But as I said in the previous post, I failed at it, because the function call towards the malware code didn't even got compiled in (the code itself was there, but there was nothing calling it), so it was harmless anyways. But again, never meant to be released to the public either.

where can we download course so we can use with this?

You can use either SMMDB externally in a browser and copy it over to the 3DS, or use the built-in SMMDB client.

Apparently, any 3DS courses converted to WiiU courses on my 3DS have an invalid checksum error when tested with pointless maker.and it causes cemu to crash because of something wrong when entering coursebot.

I'm pretty sure my checksum checking is correct.

 

[CreepyToast]

I'm pretty sure my checksum checking is correct.

then idk why all converted stages are giving me an invalid checksum error when i open them thru pointless-maker, and i have a good wii u course, no conversion and it works fine. but upon exporting from the 3ds, it turns invalid.

i would attach screengifs but my acc isn't allowed to.

Please give me some valid WiiU courses to test, it's supposed to create valid checksums >_>

here you go, the original wiiu cemu exported, and the 3ds one in the labeled folder.

Huh, very weird... can you please explain how you got each of these files? It looks so weird that the sigchecks failed this badly :/

Spoiler: screenshot

Edit: the checksum calculations were wrong all this time >_> damn, let me push an update real fast to the old version... damn this sucks :/

 

[Sono]

I updated OCDM with a fixed WiiU checksum calculation, please get it from the first post from the "releases" link.

Sadly I can't check, but OCDM can import both 3DS and WiiU levels. You need to open the directory of the level, and select "Select this directory" or something like that.

 

[Dante2405]

Can we export (or import) a full save file + extra data from a 3DS to an other with OCDM?
