Had you made any modifications to the *.exe prior to attempting to edit it in Sue's Workshop (i.e. imported custom org music, opened it in a different editor)? If so, that might be the problem and you might want to revert back to the original Doukutsu.exe. Sue's Workshop seems to be fairly picky about the *.exe files it edits.

 

imported org music just "corrupts" the exe once edited w/ sw. it doesn't give that error.

 

Downloaded a new file and it worked. Thanks!

 

anyone know why the top of the stack is made the base at the beginning of every function, then is made the base again at the end?

 

It basically means that each function has its own stack to use, and can't accidentally fuck things up, so if you push more things to the stack then you pop off it, when the function returns to the caller the caller goes back to using its own stack, and won't get confused by the leftover bits from the last stack. I wouldn't recommend randomly pushing and popping too much anyway, though, I had to give up the Weapon Hax because of some strange bug that I think was caused by messing with the stack.

 

that's interesting, stinks about your hack tho...

 

okay, problem, this

MOV EAX,DWORD PTR DS:[49E6D0]
MOV DWORD PTR SS:[EBP-1C],EAX

only moves the first byte, nawt the whole word. any ideas why?

 

No idea. They should both be moving dwords. This is using OllyDbg? It looks that way, at any rate. What method are you using to confirm that it is only moving the first byte? If you aren't using breakpoints + step through I would try that. Testing it by observing the effects in game doesn't always work as expected.

 

yep, olly.
I'm just testing the game (no fancy shmancy breakpoints), but the effects are pretty clear. this code sets the max moving speed to your health, and with a health of 812, which is the normal moving speed, you move much, much slower. if ya wanna see what I mean, jut inject this code at 41571F. it overwrites some stuff, but that doesn't matter.

I guess I could mov [49E6D1] to [EBP-1B] afterwords, but that seems like a waste.

in other news, I'm still trying to get jumps to work. you gotten it yet? I found a new method, but haven't had time to test it yet.

push destination segment
push destination offset
retf

 

Just tried it, and when I put a breakpoint on that command after setting my health to 803, E8 was put into EAX after that line instead of 32C. But, isn't there something that limits your health to 128 or 256? I'm guessing that whatever is doing that limiting is also causing the problem.

I'm assuming you want to make your mod have speed boosts instead of health boosts, and I think the simplest way to do that would be to do a SHL on EAX by about 6 before making your speed equal to it. Your method even leaves a few NOP's left over that might be enough to fit it in.

As for the jumps, no I haven't got it to work yet, whenever I needed some space either the weapon or npc that I was hacking I was removing some functionality so I could use that space instead, so there was enough pipelining I could remove that there was enough space left over. Also things like replacing ADD EAX,1 with INC EAX saves I think 5 bytes, so I never needed space outside of the function I was changing.

 

Yep just tried SHL EAX,6 and it works like a charm. 6 may be too much, though, maybe 5 would work better.

 

I put in a chest for the fireball but its not working it just shows an empty chest floating one tile above where the chest is supposed to be here the script

Hmm...

Did you use the "Closed chest", NPC 15", to start with? It shouldn't be placed above the ground, only NPC 21 "Opened chest" needs that.
Also, your flag jump seems to have an error, shouldn't it jump to event 0103 instead of 0101?

 

I did everything except the flag jump part but i already fixed the problem by having santa there and changing the text to fit the mod

I have another question though how do i make a boss fight with the first balrog I found the entities for the cutscene balrog and the running balrog but how exactly can i make him talk then attack??

 

Have you been looking through the original script? You can learn a lot from that...
Just for an example, let's pull out Balrog's first boss scene....

Now, you're probably going to come back and ask how to make him talk after beating him.
If you'd continue looking at the original stuff, you'll see that entity 0400, Balrog, has flag bit 0x0200 set. That's the "Run event upon death" flag. When Balrog is killed, event 0400 will run.

See?
Note that the usual death things will not happen when this flag's turned on. {As in, the enemy won't die, and he won't give off Exp triangles; you've gotta do that yourself}

 

Thanks I got balrog to work a few more questions though how do i make it so some blocks appear when you step some where and how do you make them disappear?

The CMP or CNP commands.
Read this for more details on which to use.
Also, add me on MSN - I'll be happy to answer any questions you might have. =D

 

I made an H/V trigger and gave it event #0400 and Flag 1500 and when you go into the room its blank and you hear stepping noises heres the code

Maybe you need to use <FAI ??
