Luigi's mansion hacking shenanigans.

M'kay.

Ok, I'm back from editing Mario's Mansion (Fixed the cowering & being hit by boos that breaks the game). Now I heard ~Scary Basher~ wants to know how to use the hex editing stuff for .prm files.

---

Here is the rundown:

-First, you read from left to right.
-u8 means 1 characters, or, in Hexadecimal, 2 digits/slots (0x12)
-u16 means 2 characters, and in Hexadecimal, 4 digits/slots (0x1234)
-u32 means 4 characters, and in Hexadecimal, 8 digits/slots (0x12345678)
(btw, the 0x part means it's hexadecimal, just so you know)

Here are my .prm file notes:

Param File Notes:

ParamHeader //the first thing on top. Only one of theses per file
{

u32 itemCount //How many param items are in there (how many variables they are in the file)


}

Item //a property of a .prm file. the amount varies by itemCount.
{

u16 Hash //Just the number representing the parameter value. try not to change this.

u16 characterCountForName //How many characters the name/string of this value is going to be


characters[characterCountForName] //the string, with the length of characterCountForName

u32 byteCount  //How many bytes the value is going to be (ranges from 1, 2, 4, & 12)
byteData[byteCount]  //The value/property you are going to edit.

}

And that's how you should read it using a hex editor. Any questions/clarifications?

Well I'm no expert on hex so could you explain what line to edit in the ghost's file?... I feel dumb asking this seeing how everyone knows hex better then me. :-/

1. Everyone is not better than you. It's a hard process to learn. And I can only read a few files completely (One of them being .prm files).
2. Where are the ghost health files, and what property to edit.

Let's just start off with where are the ghosts files.
-Ghosts health & attack stuff will be in "ctp".
-Item properties & other random stuff is in "th".

Then, we will edit "yapoo1.prm" for practice (That is the gold ghosts in the parlor. It somehow does not affect the training room ghosts)
Let's open HxDen.

This is what the file looks like.

If we edit this property:

Then we can edit the health.

So to do that, we just read after the string the "00 00 00 04" property, and select our value:

This is the value, 0x0000000A (which means 10 in Hexadecimal)

If we want to convert that, we will have to use a Programming Calculator. Luckily, Windows comes with one by default. (Just go to the settings and look for programmer) (I'm also using Windows 10)

Now we can put our custom variable in!

Lets set it to 50 health:

From Decimal 50 to Hexadecimal, 0x32.

Now we can put in our custom variable:

And now we have it inserted. All we need to now is just save, compile, and run, and the value should be changed.

I hope this should help.

Really helps! I knew how hex numbers worked I just needed the location. Thanks sooo much!

Sweet, Lukie, your tutorial comes with a lot of pictures as well.

[Lukie D]

No problem I just wanted to make sure you understand the whole thing. (And others when reading this post)

And the reason it doesn't effect Tue training ghosts is because they have separate prm files.

You can tell that because they don't attack you but taunt you.

I did everything right... at least I think I did and it crashed upon startup!

[Lukie D]

check the param folders if the hex editor made a backup copy file (it should have a .bck extension on it) of the file you edited. Remove that backup.
Also, it could be a number of things causing this to crash on startup. Checking your event scripts and model files and other files for any misnaming/extra stuff is a good idea. Also, check your extension names to see if they are correct. "ex, game_usa.szp, luige.arc in the game folder, etc."

[~Scary Basher~]

Maybe I left an extra file in there. If it happens again later ill let you know. I can be forgetful sometimes

[~Scary Basher~]

I know. And the ceiling surprise ghosts doesn't have one but has code for running away. Probably because the ceiling surprise is the basher's code modified but with a different model.

Oh and I think I discovered something! I commented on absolute g's vid a week ago and said this:

"
I have a great idea! Well as you know most of the songs in luigi's mansion is made up of built in sequenced instruments in the disk right? Well if somebody could rip and decode every single track it could be possible to edit the notes using a tool similar to a midi editor made specifically for gamecube music fonts! The beta track could be restored! (At least a portion of it) please comment if you have any interest in my idea."



what do you think about this? Did I hit something there?

[~Scary Basher~]

im getting the hang of scripting!

[TheHappyFaceKing]

Could you please tell me how to change the damage the ghosts do to you when they hit you?

Id think they would be part of the param files but I cant find it.
