Quick Modding/Hacking Answers Thread

ok, So i'm attempting to apply the WAV org hack and i'm experiencing some issues.



first of all I make a copy of my exe and place it in the folder of the hacking stuff.

then I make the changes to the instruments that I please.

after that I atttempt to assemble the thing through the run me bat, but when I look in the "read me first"

it says this...

It says to apply the assembly binaries, but they weren't in the folder to begin with so I can't do it?

 

have you tried looking in the hexdata folder

 

have you tried looking in the hexdata folder

Yes, you apply those before you use the run me?


Now it's giving me these errors in the log file

[02 Mar 2014, 09:52:59]

[FileNames]
Exe=.\Doukutsu.exe
SaveAs=.\Doukutsu_Final.exe
Log=.\Log.txt

[Commands]
Error: ".\Doukutsu.exe" does not exist


And I'm extra sure that it's named doukustu.exe and not doukustu.exe.exe


E: WOW, I'm a wonderful speller.

How does the games graphic loading cycle work?

Where do I start to learn reverse engineering?

 

Yo, I'm having this problem with Booster's Lab:

Every entity from #30 onwards shows up as "unnamed". As you can probably tell, this gives me a pretty limited selection.

What's the deal? I can't tell why this is happening.

It seems that your entityinfo.txt is corrupt.

Try re-downloading the program.

Awright, that did the trick. Thanks a bundle, guy!

New question; is it possible to give the Polar Star the Machine Gun's ammo system? As in, regenerating instead of infinite?

If you mean limited ammo, then you can through TSC



<AM+0000:0000





But if you want it to regenerate, then No, it isn't possible without Assembly.

Now, I've got the WAV ORG hack up and running and it works until I attempt to throw in my custom WAV sounds.



The WAV I'm attempting to import is 108kb, it's signed 16-bit PCM and replaces the CAT drum.



Everytime the WAV is suppose to play, it just plays the wrong drum sound, or nothing at all, but when I open it with ResHacker, it plays just fine.



If it helps, I also have the <IMG and a custom title screen hack applied.

I'm fine with doing ASM stuff, but I don't know where to start.

Start here. If that turns out to be too complicated for you, then you may need to see more of this before you're ready to tackle ASM.

 

Foe some reason my assembler is acting up on me...

This happens when I try to run the game.

 

did you check task manager to see if the assembler is still running?

Of course it's still running.

It runs until I close the window.

(and is says that it properly assembled as well)


it refuses to work whatever doukutsu I assemble to and I even re-downloaded the program and it still won't work.

(I think it might be related to an idle disk)

 

E: figured it out, ti was a typo in the offset.

I'm just gonna post this here and see if I can figure it out.

my NPC won't dive to the left.

 

You need to swap your min and max for the left dive, since a bigger number is less than a smaller number if both numbers are negative (ex. 500 > 100, but -500 < -100 )

 

alternatively keep the arguments positive and neg eax afterwards. think that's probably more efficient.

 

is there an easier way to do this?

This isn't my department of expertise, but, can't you simply check if the first bit is active, instead of going up to the byte level?

No, the least you can cmp is a byte.

 

Ok this is simple binary logic and you really should know this but the equivalent of that big cmp group would be:

mov ecx, keyHeld
and ecx, 1
jnz :move_left

The jnz will jump if the result of the last binary logic or arithmetic operation resulted in something other than 0 (jump if not zero).

 

Of the things I can do with ASM, logic instructions I can't.



I totally forgot they exist.





That's now next on my list.

Guys, I'm still having issues with the WAV playing in my custom orgs.



As before, when I open it with ResHacker, it plays just fine.



I've tired playing the drum on track 1, 7, and 8 but it keeps playing the first drum.



And I've tried replacing the CAT drum as well as TOM4.
