Is it possible to search ARM9/overlays for file references? And by file references I mean pieces of code that load/read a file ID. And then look up what file the file ID refers too? Or do the opposite and search for specific files to see if they are mentioned (by getting a file ID from the filename somehow)?

You can calc the ExtID (the indexes the game uses) by subtracting the overlay count (0x83) from the file ID you see in NSMBe.
Then you can simply search for that intermediate number in the IDA database. If a found intermediate value is passed to a file loading function (which are all named) you can be sure your file gets loaded there. If you want to know which files an actor loads the heapCreated entry in the vtable is a place to look at. Generally all 3d related stuff is loaded there. Not too sure about other stuff but I guess so. _________________________ GitHub - Kuribo64 - YouTube |

Do I literally add 0x83 to the file id and then do search the db in ida pro with CTRL-F or something?

Yeah, I meant subtract. But what exactly is an "intermediate value"?

Posted by Hiccup But what exactly is an "intermediate value"? Basically any numeric value Posted by shibboleet strings list is your friend too, if they are referenced Only the SDATs are referenced by filename instead of ID tho iirc. _________________________ GitHub - Kuribo64 - YouTube |

Yeah, I was using the 64bit version - oops
 . Another question: how do code hackers such are yourselves contribute to the IDB if dirbaio isn't online and it is in his post? Or do you just not use it?

Is the stuff discovered by MeroMero, skawo etc in threads in this forum the sort of thing that'd go in the idb?
I guess the Newer idb will be released with the game along with the code hacks and other behind-the-scenes stuff like that? |

No idea. It's not like there is lot's of stuff that is new in our ida. Stuff by MeroMero is not in there.
So it's probably not worth releasing that (technically it would also be illegal as it contains the code of the entire game). And I'd not release the Newer stuff instantly because I'd rather see people play the thing before hacking the shit out of it. _________________________ GitHub - Kuribo64 - YouTube |

You could release it as a patch to the one dirbaio posted. And its not like its the whole game.
Btw, off the top of your head, can you think of another program that can display the same file IDs as NSMBe? I can't use NSMBe right now. |

Technically every bit you distribute of the game is illegal.
And yes, the idb contains the entire code of the game, including all overlays. And again, it's useless to literally everbody. I see nobody ever using that idb again and if somebody really does the few things we added are not hard at all to find again. _________________________ GitHub - Kuribo64 - YouTube |

Yeah, but if everyone who ever looks at the code says that then it will never get documented.

It's not like there is anything more interesting to discover. And that "everybody" have maybe been 3 people over the last 3 years. So ugh... And you
