undo the changes?

the thing is I don't know what in the world I did. -_-

You did make a backup, right?

yeah. . . but that would be in an old executable, the glitch has been around in my executable(s) for quite a while.



Well, it's not THAT bad though, just reprogramming framarects and re-applying some patches. (20 minutes of work at most)

can I, y'know, get some help with this?

 

How do I change the color of the CS font? And how do I change what the sounds sound like?

Well, if you would have read the post above you would have know it is at address 4253AD

but the sound, I don't know that one.

 

And how do I change what the sounds sound like?

Use SeaTone.

 

Now How do I import it into CS?

 

Documentation on the program is provided in the download.

 

Ok, So I'm trying to make a new TSC command, but the game keeps crashing every time I try and use it. (I'm using doukustu assembler, so you know)



here is is:

ADD EDX 8 ;add 8 to script position

JMP 004252A7 ;jump back to beginning of parser

I think that I'm doing something wrong at the end. :/



EDIT-



stupid spoiler tags won't work -_-

 

Ok so 2 things:

1. Debugging assembly is hard. This is why few people do it, and why fewer will help you with debugging your own code. Especially since it's hard to debug something you don't have direct access to. So don't be surprised if you don't get too much help with it. If you want to use black magic, you need to be prepared to suffer the consequences.

2. Ollydbg has this feature where you can run the executable WITHIN ollydbg, and then it will show you where it breaks in the ASM normally. Just load the exe and look for the little play button/icon.

 

I changed the font color green on accident
I want to chage it back to white. Does anyone have the codes I need?

it's 00FEFFFF

 

Hello, sorry if I keep bugging you but,
i'm very new to assembly and have no idea on what i'm doing.
I tried following the tutorials on this site but I don't even understand them.

There is two hacks I want to apply,
The infinite mimiga mask
http://www.cavestory.org/forums/threads/3159/

and the Max health hack
http://www.cavestory.org/forums/threads/2047/

How do I apply these hacks? Do I just copy and paste the lines one by one or is there a different way of doing it? It's really confusing to me even
with the tutorials I tried to follow. So can someone give me a step by step instruction on how to apply these hacks? Or is that too much to ask?
I would just download the pre-patched versions but there is two problems, one is that the infinite mimiga mask pre-patched download link is broken
and two is that I want them together, if that's even possible. I will continue to try and patch the game myself with these hacks but I just wanted to know if anyone
can help me with it.

It just turned red. 00FEFFFF turned red. Not all of it though...

 

What's the best way of finding an NPC's code for when they die? I presume it would be somewhere where there's a command that has something like "CMP [E_X+40],0" that compared its health with zero and jumped to what ever makes it die, but I haven't found anything of the sort. The main NPC of interest in my case is the Sandcroc.

Most NPCs don't have such code, as it's handled externally by some other function I think. Gaudis and butes are the exceptions, but you'll notice how they have 1000 hp. What they do then is compare their hp to 985 or something like that for triggering the dropping of their corpse entities.

 

Then how would I go about changing what happens when a certain NPC dies? Do you know the address for the function that handles this, or where I might find any documentation on it? I couldn't find any information on it in the assembly compendium.

I'd recommend doing it the way pixel does, that is setting their HP to something really high like 1000 and then checking for 1000-x hp in their AI.

 

I have a certain door script which is...

#0104
<PRI<SOU0011<HMC<MOV0033:0016<SMC<END

There is a problem in the game. I go to where I set it but I automatically get moved back. Can anyone help me or is this just 2x problem?

Just do this

#0104

<KEY<MOV0033:0016<END



Much better

No.



The <SOU's and the <HMC/SMC are needed for the door sound and to make quote dissapear and are completely unrelated to the problem that he has except that he should use an actual <KEY instead of <PRI.



Some solutions:



#1 He has his <MOV's incorrect.



#2 Used <PRI instead of <KEY (I think that all entity's cannot move when <PRI is used even inside of a <MOV command)



#3 Use a <TRA instead.

 

Used <PRI instead of <KEY (I think that all entity's cannot move when <PRI is used even inside of a <MOV command)

Just now tested this myself by changing the events of the doors in the hideout in CS to using <PRI, and they still work, aside from the doors not animating when this has been done.

Use a <TRA instead.

I don't think that would be a good alternative, since fadoink appears to want to teleport within the same room much like the two doors in the hideout.

I'm not entirely sure what fadoink's problem is here. I would like to agree with Bombchu's first hypothesis of an improperly configured <MOV, but I can't be sure.
