Quick Modding/Hacking Answers Thread

EDIT: did you just compare a mimiga to a horse?

Spoiler

Yeah, I guess you're right.
And it's not like I need it soon anyway.

Nor do I, but it's something I want for numerous planned areas. If I end up making it, you can have it.

It is in fact, the best way to do it. If you've ever tried to write large hacks, you'll understand why. Being able to make minor adjustments in something already written without having to rewrite half your work is a blessing to the field of CS hacks.

I've been wondering where that app stuffs the assembled code, if it was larger than the original that is.

 

prolly just overflow.
kills remaining stuff.

 

It will always just overwrite.

I wonder if it could be modified to expand the .exe though, but I imagine that would be difficult since then you would ruin a lot of calls.

 

Not if it did so intelligently, and re-ordered referenced addresses and what not. But uh, that's way beyond my ability to do... although, I do know someone who probably could, but... he has a company to run.

 

Aaaand 2000. Gosh that was quick

Once again thanks to everybody. Hope that this threads' jump in popularity is a sign of many more mods to come

 

Many more *finished* mods.
Anyway, thanks dubby.
...It seems I have a rival.

 

A rival in *what*

...don't answer that.

Anyway, yes, an intelligent patcher would be nice, but that seems a bit excessive to me. As long as you know where you're putting things and properly plan ahead, there should be no issues. It doesn't have any consideration of what the "Original" code was at all, it just starts pasting hex at the specified address.

 

So, how are you supposed to know what line of assembly does what? I don't see any clear commands like in TSC.

Oh, also, I fumbled around ollydbg for a half hour trying to change one number.
Progress.

You can't. You just have to test each line apparently.

 

What are you talking about woody?
Anyways lunar, I HIGHLY HIGHLY HIGHLY reccomend that you read one of the tutorials on asm on these forums or elsewhere. The commands you're looking for are like: mov, add, push, pop, etc. They happen at the start of a line of code, after the hex in olly.

Ouch.

Could you provide a link to one? I can't seem to find one.

 

Woodenrat's just being.. umm... uninformed. It's perfectly possible to read the assembly code line by line and understand it and I do this all the time.

Try looking at the thread titles and you might find one that says "guide" and "Assembly"

 

Thanks, man.
You're always there for me.
...Well, you are a moderator. And a modder!
Heh...I'm funny.

 

It was on the goddamn front page!
It's a sticky!

Why does nobody ever read the stickies?

 

Well, someone's a little on edge...

 

Well, someone's a little on edge...

Yeah, geeze Noxid, CALM THE FUCK DOWN!!!

 

Oh, ho, ho...funny.

I know right?

That guy's more touchy than nitroglycerin.

 

Here's an actual question:
In the ASM for cave story, there are 04000000 values. But when you start the game, they change to 07000000 values. Are the 04000000 values startup values?
It would make sense, since it has coding for weapons and TSC commands that can't be changed by modding with CE and entering a different room.

 

OllyDebug just likes to add 4 bajllion (in hex) to everything for whatever reason. So like the actual location of a line of code in the exe is whatever olly says it is minus 4 bajillion (in hex).
