is there a yay0 decoder/encoder yet? That's the big thing.

Yes, but its not mine to give away. A friend of mine made it and doesn't want me to give it out, and thats that. Edit also how do you think I did all of this, hex editing?

Whatever you want to call it go ahead, I didnt say not to give it away the person who made it did. dont shoot the messenger.

Dont worry about it, also he's a nice guy, he's just really anal about people stealing his work, even though I told him it most likely be stolen this time Also you cant really do jack shit with a yay0 compressor, you cant edit rooms or area layouts, all you can do is model swapping because the tools are not there for everything else yet

A solution would be to put his name in the tool.

And keep it closed source if he's really wary, but I think closed-source tends to also hinder progress in ROM hacking. Good documentation can compensate the lack of source code, though.

I've explained all this to him and he still doesnt want it given out.

Honestly I dont know if any of this will change his mind, hes the hardest headed person i've ever met, once hes makes a decision its unlikely he will change his mind. also as I mentioned earlier, there is no room editing, the bin files are still as mysterious as ever and our research hast turned up anything, which makes the yay0 compressor virtually useless for anything other than swapping model that are already in the game (.mdls anyway, the few bmd's can be edited but not much). Edit: the one thing we know about the bin files is that they seem to be a packed file type, thats all we know and its only a hunch, but considering other things in the game that would support it, its likely. Edit 2: and on another side note you dont need the yay0 compressor to edit the bin files where rooms are held they are in uncompressed folders in the iso so all you need to do is rebuild the iso for room editing, making the yay0 encoder even more useless

Try to google the gamecube .mdl model format, probably another game uses it and somebody would have decrypted it.

You do know that a python script was already made for it, right?

:I OK, i didn't knew that, it's posible to port a new luigi model?

Like I said earlier, no it isnt, we have mdl2obj but we dont have obj2mdl which is what we need.

If he keeps shit to himself, people will consider him a fake and a lamer.

Either way, maybe somebody here can try it out.

Try what out, obj2mdl or a yay0 compressor

An mdl2obj is the only useful thing right now, a yay0 compressor is barely needed, what is needed is a way to decompile .bin files (which you dont need a yay0 compressor to reinsert into the game [see Iwamoto folder, just edit and rebuild iso], the bin files are rarc compressed at most). Also Lm hacking community? the 5 people who use hex editors and the few that have the yay0 compressor? im sorry but if you think there is an LM hacking community you are sadly mistaken, its like 10 people at most.

There's already a yay0dec, irrc.

I mean .bin files, which are not yay0 compressed. Also if anyone really wants to know what you can edit with a yay0 encoder look here http://pastebin.com/xv8U7pkA

Well after working on this for a while and forgetting to post about it here its finally done. this is the Luigi's Mansion boss rush hack and as the name implies its a boss rush, all the bosses are fought on one health bar and are one after another, no breaks. the only issue is it doesn't immediately start when you start a new file so you have to do the training room but there isn't much that I can do about that right now. Here is the release trailer (download is in the description of the video) EDIT: I just want to specify that I made this using my own yay0 tools, not the tools made by NWP

I could easily just tinker with Anarchy and make it a Luigi's Mansion editor, but I don't have a clean C# library from Anarchy.

I really don't want to use Anarchy2's library, either.

Not really, editing the jmp is one thing but editing the collision is another, what you have to remember is that the models like dressers tables and couches are built into the collision models. In short, no, an edited version of anarchy could work as an LM editor because the JMP and collision need to be edited separately.

Yeah exporting the models is fairly easy, I could dump some 3dland models if you need rean, ive got a dumped 3dland rom

I mean dumping/converting them to obj, sorry if that didnt get across right

Are you using smea's cgfx2obj script, the nosies importer, or something else? I usually use the cgfx2obj script

____________________

yep thats the one!, it screws up models sometimes so i'd just use the nosies plugin or whatever you've got going right now :p

That is freaking awesom rean!! Please show some more pictures :PP. HOw did you manage to do it?

There are scripts (like the one mentioned above) for model dumping and you can dump 3DS games with xor pads made with some 3DShomebrew running on firmware 4.5

How do I dump the files? I have Gateway and a 3DS with FW 4.4. What else do I need? What is the process?

Go to GBATemp there is a whole thread about it in the 3DS section right here http://gbatemp.net/threads/extracting-models-and-textures-from-3ds-games.370788/

But I still don't understand how you did round trees and shading and shadow if you were using SketchUp. I thought SketchUp couldn't do that.

Sketchup can be a very powerful modeling tool if you know how to use it right.

But actually understanding the format itself? No.

What format exactly? You don't really specify in this post, and if you mean bcmdl/cgfx models, then no. They are well documented, understanding the format isn't as hard as you are making it out to be.
