OCDM - Mario Maker 3DS course manager

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

Not sure if this is dead or not, but anyway I want to inform about the Wii U homepage for sharing loadiine/Cemu ready courses.
http://smmdb.ddns.net/
It also has an incomplete API, that I am still working on. It will have all the functionalities of the original homepage.
I am the creator of this homepage, if you have any questions

Sooo, the DL links in the OP are now broken. Is there are mirror for the .3dsx version at least?

Here is a direct download (courtesy of wololo.net): https://puu.sh/sBngv/e3e350bd2a.3dsx

EDIT: Found source: https://github.com/RepeatingEpic/OCDM

Could it be possible for you to host 3ds versions as well as Wii U versions?

Don't think so. MarcusD effectively left the 3DS Homebrew scene, and the source repository has been deleted. I'm guessing the only reason HorizonM (the sole 3DS project he has the source currently available for) is public again is because NTR streaming broke in 11.4.

Well, it appears that someone might have downloaded and uploaded the source, link is two posts above yours. But I do agree, I don't really see this getting finished. Which sucks cause I really was looking forward to having a way to share all my levels on the 3ds version. Play it a lot more than my Wii U. But you never know, maybe someday some one will pick it up.

Marcus didn't left the 3ds scene and he is actively working on HorizonModule. As a beta tester I can definately say HorizonModule did a great progress in the last few days.

I've been looking into this, and it seems like the file course220 is the key to making everything work. It's the check file to make sure nothing is wrong.

At the end of the file you see 00 01 02... etc. For every level you have made. The rest of the file, I am trying to figure out, if there is a correlation between those numbers and the level files

o rly? I'll have to look into it again then! I thought course220 is just used for checking the header, and the rest of the file is just uninitialized from expanding the ExtData file to block boundary. well, once I'll have time I might look into it again then, but don't take my word for it; I still need to find out the CRC used in the first 4 bytes

I'm trying to figure that out too :P

Another thing, if you download a course through courseworld, it skips the number in course220. For instance if you downloaded one as your second course but made more afterwards, it would say 00, 02, 03... and so on.

Marcus said when he has time he might look into it, if you can read that is, so IT MIGHT BE alive in the future.
WARNING: Anything that is not a definite yes or no is not in a noobs vocabulary. Question repeat incoming on next page.

From what I've found, downloaded courses start at offset 0A0 and block 00. If you remove the downloaded course though, it doesn't delete it, it just changes the offset block back to FF

--------------------- MERGED ---------------------------

The only parts that seem to matter in course 220 are offset 000 blocks 00 through 02 and offset 020 blocks 04 through 07. I don't know if what is in between is device specific, or if it is generic.

--------------------- MERGED ---------------------------

Just tested and found out that if you copy over course220 with another course220, and the courses that you added match up, it will add those courses to your coursebot and you can play them. It only works if you overwrite all of your courses, it does not work if you try and just add one.

Instructions for saving courses:
1) Open FBI
2) Navigate to super mario maker external save data
3) copy all contents to clipboard, if some give an error, don't worry
4) make folder on sd card
5) paste contents to sd card

Instructions for adding courses:
1) Same as saving except paste courses from folder into external save data

--------------------- MERGED ---------------------------

Here are my courses that I know work: http://pan.baidu.com/s/1jHRPCCQ

Click on the button with the down arrow to download.

If you are downloading all at once click the download button and then the white download button

Note: you have to open the folder first before downloading

    @K3Nv2 Snow Day is pretty fun. My only bitch would be the camera controls, when you move around, say down, you have to move the right stick left or right to get camera to turn and get your view, other than that I like it so far.

    From what people say pvp isn't even worth it
  • BigOnYa @ BigOnYa:
    I just been playing offline, and they give you a few bots here n there on your team to help battle. I don't think it's as funny as the other games tho, more battle oriented than humor, which kinda sucks, but I'm still early in it
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, doesnt the game have a campaign mode?
  • BigOnYa @ BigOnYa:
    Yea, and co-op, but you can also start a pvp session and battle just with friends. You get special skill cards (powers) the more you play. And higher value cards, but you can only enable so many cards at a time.
  • K3Nv2 @ K3Nv2:
    If you can find enough for it
  • BigOnYa @ BigOnYa:
    Toilet paper is considered the money, you collect and buy stuff with TP, kinda funny. Graphics are def better than the other games tho, I think they used Unity 5 engine.

  • SylverReZ @ SylverReZ:
    Likely because black and white TV was in-expensive.

    It certainly wasn't inexpensive it cost the same as a new car back then
  • K3Nv2 @ K3Nv2:
    How much did a 1965 color TV cost?

    For example, a 21-inch (diagonal) GE color television in 1965 had an advertised price of $499, which is equal to $4,724 in today's dollars, according to the federal government's inflation calculator.
  • Xdqwerty @ Xdqwerty:
    @K3Nv2, take into consideration how economy was back then

    Yeah that's why they listed inflation rates
