Visual Basic 6.0 HEX Editing Functions - For Hacking ROMs.

[D-Trogh]

Sorry, D-trogh, I didn't notice, well, its fixed now. Thanks alot, I'll credit you.

One more thing how do you use the reverse hex for writing pointers?
eg.
"21348008"?

You don't need to credit me.. Next time just try and read, k?
And, to answer on your question: ReverseHEX(HEXString) will ^^
So ReverseHEX(08123456) will return 56341208

Good Night (2:30AM !!)

yep, so far everything's working fine,
Now, I need a code that does this:

there's a textbox(named txtR)which is used for inputting offsets(6 digits), I need a code that changes the number value in the textbox to decimal, so I can use writehex, romlocation, "offset" how do you do it?

WriteHex ROMLocation, CLng("&H" & txtR.Text), Data

That should do it.

 

[ZodiacDaGreat]

That should do it.

Worked again!, now how about a code that checks whether theres a value in the textbox, in my case txtR. So there wont be any mis-compilation of bytes into the ROM

Thanks again, Darthatron

If Len(txtR.Text) > 0 Then
    WriteHex ROMLocation, CLng("&H" & txtR.Text), Data
End If

The Len() Function checks the length of a String. It is used mostly for checking if you have any data held in a Variant. :D

The code "If Len(txtR.Text) > 0 Then" checks if the Length of the Data in the String is above 0. 'If' it is then it will do the code before 'End If'.

It was a great Idea to make this Thread. Especially for me!
I have a question, will these commands work for Visual basic 2008 Express edition? Because I can't find VB 6.0 anywhere!

Oh yeah, another thing, As long as you have the data for the Rom, you can make tools for it right?

No, I don't think they will work with VB 2008. Although these languages are similar, they also have some major differences. When I get time I will try and make functions for .Net 2008. :)

Hey everyone. The development of new tools is coming along at a simply staggering pace now. I wish to add my own to the mix!

It is a RBY gym and elite4 editor.

It reads data from the rom ok, but writing it back is the only problem. We all know (well most of us) that a Pokémon's "hexbyte" only lasts one byte in RBYGSC, but whenever my program writes, it writes 2 bytes, and erases the byte after the desired one aswell. Does anyone know how to get it to write just one byte?

Thanks

 

[ZodiacDaGreat]

Yeah, Thanks to this thread, I've made my first tool, which is in the toolbox.

Bravo! Darthatron!

WriteHEX LoadedROM, Offset, Right("00" & Data, 2)

That should work a charm. :)

how do u make other tools such as a tile editor

 

[Darthatron]

Well.... You would have to decompile the actual tile image and then get the program to read it and make it editable, then work out how to recompile it and insert it into the ROM. :)

Good luck, I don't know how to do it.

 

[Swampert 22]

Thanks Darthatron buddy, I'd tryed that but it hadn't worked before, I think I didn't Dim LoadedRom as String???

Thanks again. My tool will be out soon!

oh i dont understand it that much but thanks anyway

Where do I make it the tools? In which program?

lol, a programming language of course, people here mostly use VisualBasic 6, just as the thread suggests, a download can be found if you search at wikipedia, thats where I found mine.

It isn't simple though, to code

 

[X-Buster]

and how do you use it?

[Game goer]

sweet! I finally fulfilled my dream of making a tool! lol

Darthatron, do you mind if i take this tutorial for a youtube video? I'll give you all the credit!

This is pretty much useless to me, because I've like mastered VB and already know ROM Hacking: This just uses methods that contain Get, Seek, Put, Open, etc... And here's my main question: I need to know how to hack graphics. Get this: I've been trying for almost a year now. I've tried the set pixel method, Line, etc... And looked at so many sources, even the EM sources and I can't grab graphics. I went to Jathy's IRC channel (Creator of SMILE) and tried to learn to graphics hack from him. He just explained to me what I needed to know, the format of the gb/c/a, and that just made it worse, because I already knew the format of the graphics. I've edited the graphics of a ROM via hex editor, like I did in Zelda LA, and I can't display the graphics in VB. I just don't know how to check the byte on an offset and display that pixel. I know how the hex editing works, byte pairs, offsets, etc... And the format of the systems. I was wondering if you knew how and could teach me; I've gone on long enough without knowing... Thanks, and sorry for the super long reply for a simple question :)

EDIT: I already know you use ASM for uncompressing the graphics and then recompressing them, but in the games I want to hack, such as Zelda LA, a bunch of the tiles aren't compressed. So I just need to know the method...

I'm using Visual Basic 2008 Express edition, does anyone know how to create a ROM Hacking tool in this program?
