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

So you recovered all your courses by only creating one new course?

You just need to create one course so that you can copy the id (the bytes 0x10 to 0x17) from that file and paste them to your old course files. If you do that and import the courses back into the game they will work.

Makes sense. You need to initialize your savefile before you can import them with OCDM.

The reason OCDM still doesn't have a backup restore functionality is because of the savefile itself. Good luck restoring that.

Other than that OCDM could very easily restore the levels themselves, but I figured that would be pointless, because I'm pretty sure nobody wants to go thru' the tedious process of unlocking everything again.

 

[Reynardine]

Hmm, I avoided that because it was only my SD card that failed. I still use the same 3DS with a different card.

After I inserted a new SD card I could import my backed up 100% savefile with JKSM and it worked, only the courses didn't because they are tied to the SD for whatever reason, so I had to manually edit them.

Is there some place online, perhaps a Discord channel, where one could request a few levels to be uploaded on the Super Mario Maker Database site?

There's a discord server link on the SMMDB website.

That's good to know. Luckily it sounds easier than I thought. Luckily this SD I have seems to be working fine after all these years.

Huh, this is also good to know. Wish the Cemu Mario Maker wiki wasnt dead though.

Also I know you're working on this in your own time so no rush but dang fixing the thumbnails would be super helpful, even if its just to make the level names not blend into the other tile

I'd need a JPEG encoder/decoder for that, and OCDM is already way too big. I don't want to work on the current version, I want to do the rewrite instead.

Remaking the whole thing? I mean of course you know best what to do with this so it's not like there's much I can say on that front.

Yeah... current OCDM is shit, and doesn't even support Japanese characters, and it doesn't look anything like the original OCDM design. I want to make OCDM what it should've been in the first place.

I did notice that I had to change the name of Japanese levels just to import them because otherwise it doesnt work. And then the names are jumbled regardless. In that case good luck then.

Hi! I just installed the .cia of OCDM and I started it up and it stopped at "[GAME] Checking game cart", then it says that the application has crashed and then it has a result of C880448D. Thanks in advance!

That is a known problem. I just currently wiped Windows, so I can't upload the "fixed" 3dsx yet. But it will most likely not work anyways. I have no idea why it doesn't work, I already tried everything to try to fix it. Sorry

This is new to me & I see it's a old post how did it go

Wait if this is a problem that was never fixed how has it never happened to me?

It seems like SMMDB was updated to TLSv1.2, but the 3DS only supports up to TLSv1.1, so this is a server-side error.

I would ping @Tarnadas, but it seems like he's not on the site anymore.
Edit: or just GBAtemp being buggy

Not without me remaking OCDM's networking code from scratch. This has to be done server-side. I can't fix it.

It's seems i have to manual download on web
Could you tell me how do i import zip in OCDM? or Level file must be .3ds?
at smmdb.net, if i wanna download .3ds file, i have to scan and recognize QRCode..it's too troublesome..
or is there any another ways to download .3ds format?

SMMDB should have two download buttons: one for WiiU, and one for 3DS

If you have a WiiU level (usually in a zip), unpack it into a folder like this:

• levelname
  • course_data.cdt
  • course_data_sub.cdt (optional, but required for levels which use pipes)
    
  • thumbnail0.tnl (optional, unused)
    
  • thumbnail1.tnl (optional, unused)
  • sound.bwv (unused)

No matter what, you need to import a 3DS level into a slot first! Tap a slot to open the dropdown, and tap the "Import 3DS" button, browse to a level, and import that, then B to exit the level selector.
Tip: export a level you made, and you can keep reimporting that over and over again.

If you want to import a WiiU level, you need to import a 3DS level first, exit with B, and re-enter! Tap "Import WiiU", browse to the folder where course_data.cdt is, and tap "Select this folder" at the very top. Then once again, exit with B, and re-enter to see the changes instead of a glitchy mess.
