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

could a course editor also be done so we can do glitchy things that can't be done normaly in mario maker

it could be done in a separate app, but ye, it should be doable (from the level file perspective, because for that we can recalculate the checksum)

 

[hacksn5s4]

could a level converter be done like conver super mario flash levels to mario maker

Im pretty sure nothing like that will ever happen. We will be able to upload levels to a 3rd party site and upload them to our save with this app I believe.

Pretty nice, we should wait some time before seeing some course exchange post/site.

I'm making a level "based on" Mirror's Edge, i think is pretty decent, but since it has a lot of blocks and stuff i get framedrops when traveling the whole level for edit, and 1/2 sec lag when i do or revert a step (O3DS. I'm sure N3DS shouldn't have this problem). Pretty noobish since is my first level, but i'm proud of my Frankenstein.

 

[Polarise]

Works well! When will you update it and make it a cia?

 

[Svaethier]

Do we even know how the game handles levels in ext data? Simply sharing your ext data which has the level files in it doesn't work :/

I think it might be linked to the save file. I backed up the save data using JKSM and removed the game, and upon redownload I chose not to remove the extdata and restored my save data using JKSM and was able to play the game using the old courses I made before removing the game.

I am to dumb to download the 3dsx just getting redirected to a website

 

[PRAGMA]

Please Github it asap so others can help development!!

 

[EventAssistant]

Meh, I just loaded it and it crashed. Do I need to load it with the game itself, with a xml?
EDIT: same with the xml
EDIT2: I saw your post regarding the app doesn't work on EUR saves, I'll wait!

Ye, your LockoutID is also stored in the savefile as well as in course220... I wonder if corrupting course220 will bork up the entire savedata, whereas borking up course000 will only bork up that course while leaving your whole savefile intact.
Also, I think I found a way to inject others' courses while leaving them intact (so it'll function like if you got it with StreetPass), I'll just need to recalculate the savefile's hash.

I'll put it up as soon as it's stable (aka. doesn't blow up your entire progress)

It shouldn't crash! But I know what crashes (because sometimes I behave like I don't know jack shit about how the 3DS's system works). It should be fixed in the next public build

Alrighty if you need register's dump I can give you 'em all

Nah, as I said, I have already fixed it It was just a copy-paste oversight from TerraInveditThreedee

I'm so hyped for this project! I love making courses but I have no one to share them, so what it's the point? I don't know what Nintendo was thinking when it decided to remove "course upload" from the port. It just killed the point of the game.

 

[Sono]

I am to dumb to download the 3dsx just getting redirected to a website

You shouldn't be getting redirected Try "save as" on the 3dsx download link, that should be working.

The only reason I have stripped the features that write into the save file from the public build is so those who can't read don't ruin thousands of savefiles just because they can't read Sorry

Nice will try it out.

Right-click on it and click on "Save as file".

 

[PRAGMA]

@MarcusD what are you coding it in? C or CPP

 

[MikominMM]

For some reason the thing doesn't work for me.

It says:

------------------------------------------
Hello!
[MAIN] Searching for Mario Maker 3ds exdata...
[EXTFS] Can't open exdata: C8804464
[EXTFS] Can't open exdata: C8804464
[EXTFS] Can't open exdata: C920181A

Can't find any Mario Maker 3DS savedata!
Welp, fug... :/

Press a key to exit...
------------------------------------------
And it crashes right after.

I clearly have a copy of MM3DS on my Sky3ds And the save, so why it isn't reading it!? (My Game Region is EUROPEAN)

Did you actually have any courses saved into Coursebot?
