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

I'm greatly pleased this project is still alive, please keep it moving- the end is in sight. If you have to release this without an in app server I'm sure the community would still be perfectly fine with a way to import/share levels.

Why?

 

[Tarnadas]

@MarcusD I am currently implemeting the conversion 3DS <-> WiiU.
Do you know anything about the thumbnail format?

3DS<-->WiiU is already implemented but whatever

yes, on the WiiU version it's just an 8byte-big -header -prefixed JPEG, on the 3DS it's just a Morton-interleaved ("swizzled") 168x216 and a 32x240 RGB565 thumbnail rotated to the right

Why?

it means "can't open ExtData because it doesn't exist"... did you ever get to the coursebot before opening OCDM? you need to have a valid savefile before being able to open OCDM

Thanks, and no. It's only implemented in C, but I have to use it either with a CLI or I have to port it to Node

wait what are you talking about?^^
Can I somehow use this on a Node server?

oh ._.

sorry then


uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuh... can you understand C# ? I guess you could try porting it to JS

That's actually what I'm doing. Node is just on top of JS

wat

are you porting C# code to JS?
also, I know Node.js is JS I'm using it

(I have a feeling there's a serious misunderstanding in this conversation, but it's prolly my fault for losing the context)

I think so too
I am porting your code to JS. I don't know C# a lot, but isn't your code C (which I don't know either a lot)?

yeeeees, but the thumbnail creator/importer I quickly made is C#, because I have previously worked with raw image files, so I just repurposed some old code for creating a png and importing a png into the course files

Where can I find this image importer/converter?

Edit: Oh well, I just found this: https://msdn.microsoft.com/de-de/library/windows/desktop/dd390989(v=vs.85).aspx
So I just recreate the bitmap from this?

Ok 3DS to WiiU conversion is partially working:

hmm... I could try making that Morton (un)swizzler in JS... umm, is the "jimp" Node module usable for you? because if I really do this then I'll base my code around that

edit: I have also noticed a flaw in your code... the WiiU version uses standard CRC32 outputted in Big Endian order, whereas the 3DS version uses ZIP(?) CRC (aka. CRC32 with 0xFFFFFFFF as the initial value instead of 0x00000000), and the result is NOT'd and written in the file in Little Endian order

So , what i need to do , in short ?

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

But strangely enough , the old homebrew version works pretty well

have you tried the current homebrew version? the homebrew version has a slightly different filesystem implementation, so it may work

also, by that I meant that you need to open the game, wait for the main menu to load, and go to coursebot, and then press the HOME button and close Mario Maker. this is the least effort you need to make in order for OCDM to be usable, otherwise you'll get errors on startup similar to this

Yes I already use Jimp.

I also implemented the exact same algorithm as yours and got the same result as with the standard Crc32 algorithm. I checked both crcs before and after conversion and they were the same. I just had to use LE

Can you post me the QRcode download of the latest 3dsx version ?
