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

Back them up using a normal save manager.

You need to back up both the normal save and the ExtData as well.

I'll try to figure something out in the meantime.

Thanks a lot!

@Sono Do you have the source code for the the latest version of OCDM. I looked on github but I can only find that for v0.4 and the latest seems to be v0.6. Is there also a changelog?

I still have the source code, but it's not public.

There is a changelog *somewhere*, but I'll have to dig it up.

Will you share the source code? It's fine if you don't.

 

[baby_gakuin]

this work now?

Not sure. What parts do you need?

this work now?

It always has, kind of.

SMMDB integration is definitely broken now though, and has been for years now.

I find this too late...

You can still download them manually and transfer the levels to the 3DS SDCard.

Actually, I think SMMDB integration *might* still work if they didn't enforce TLSv2.0 requirement (3DS only supports TLSv1.1 in sysmodules, only the web browser supports TLSv2.0 by bypassing the SSL sysmodule and doing networking manually) then it would most likely still work.

No, sadly adding TLSv2.0 support is absolutely not trivial.

Is there a web to download the levels?

Yeah, it should be http://smmdb.ddns.net/ if it still works.

mnnn dont load on my browser

I really just want to poke around with the code and see if I can polish it up so really whatever you're okay with sharing. Though the netcode is not of interest to me.

https://smmdb.net/courses

Though those are reuploaded by other users. If you go here you can find how to download any level from the backup that was done after the upload course feature was stopped.

Ah.

Yeah, not sure that's a good idea all that much. "You can't polish a turd" as they say, and this sadly applies here as well >.<

Not sure what there is to "polish" about it, considering how bad everything is, including the code, the UI, and basically everything about it.

Fair enough, I won't bother but I do want to understand how it works though, because the reverse engineering work has obviously already been done and OCDM really had potential to fix SMM3DS. Is there some documentation anywhere? Could you share it anyways? After all, an older version is out there.

Oh, if you want the file format, I'll be more than happy to share all of the technical details and challenges, I just don't know how and where.

I have actually cut out the guesswork, and went straight into the game's code to reverse-engineer all of the structures, so unless I've overlooked something (if I did, the game would just crash, so probably not) it should be 100% accurate.

Ah okay. So I imagine it should be present in the older version then. I'll try to figure it out from there then. If there's anything I'm unsure of, I'll let you know. Thanks!

I think I did changes in v0.6 to the internal structures, since sometimes I got a data abort in older versions due to janky code, so be cautious with the old public version.

Hi! I just find out about OCDM but have a question. I can only find builds marked as old or legacy. Is there a new version somewhere or should I stick to legacy build from download section here on GBATemp?
Is OCDM still works? I only want to export custom levels from SD card to the game.

It's being rewritten indefinitely.

It's okay to use the "legacy" build, it just means that it has the "old" UI.

SMMDB most likely doesn't work though. Everything else (local) works just fine.

Hi maybe this isn't the right place to ask, but I thought maybe this tool could help me? I'm trying to fix my son's save data. I'm not sure how this happened, for some reason when starting Mario Maker, he gets this error about the software using an SD card not paired with the system. Then it wants to re-create the ext data or it won't let you boot the game.

I have his extra data backed up with checkpoint, but restoring them just causes the error to reappear. I tried using OCDM to create a snapshot and then re-import one or two of the courses on a fresh save, but as soon as you load course bot it says the level data is corrupt and removes them.

I'm the one who hacked his system and set it up years ago. He knows only enough to play the game, so I highly doubt he himself has done anything to corrupt his save data so I'm really puzzled as to what could have happened to his levels. He'll be crushed if he loses them all, but I don't know enough about how this works to fix it beyond what I've already tried.

Sorry to bother you guys. I know this might not really be the right place, but my searches led me here and I had to ask.
