================================================== ======================
Elf modifier v1.2
================================================== ======================

Basic overview:
This app allows you to modify the elf headers (main, programme and section).
Also allows you to modify lines of code in the elf.

*Notes*
[1] The set Header and Programme header buttons will use both the data from each tab so be carefull
[2] you will need .net run times sorry
(http://www.microsoft.com/downloads/d...displaylang=en)
[3] Address for moddifying is calculated by:
Finding the first address of the elf in the PS2Dis (not the entrypoint) generally 0x00100000.
Subtracting this address from the address you want to edit (0021044C - 00100000 = 0011044c)
[4] Backup the elf first incase something bad happends.

[5] code text file looks like:

2
0x000000e4 0x24426e40
0x000000e8 0x20000002

format:
NumberOfCodeLines
Code1[space]Data1
Code2[space]Data2
etc...

Change log:
V 1.2 (31/10/06)
[1] Added a GUI.
v 1.1 (31/10/06)
[1] Added support for reading a code text file to add to the elf.

Nice job man......I can't wait to play with this this weekend. I'm getting the feeling it's going to be useful.

lol thanks its 10x easier than a hex editor especially with the code files

[Lazy Bastard]

Nice; this may solve my problem with CCheat

I'll add this to GSHI's Downloads section, with your permission. Also, feel free to use the attachment function of the forums.

[Edit]: I believe you mean http://www.microsoft.com/downloads/d...displaylang=en as the other link was to .net 1.1.

[Lazy Bastard]

Also, if I wanted to change the value at 0x00400770 to 0x00000001, I would choose the input elf, choose an output filename, use...

1
0x00400770 0x00000001

...in the main box of the Edit File tab, then click Set Codes, correct? I can't seem to get Elf Modifier to output a file (well, it makes a file, with 0 bytes filesize)

[cYs Driver]

well the input elf will also be the the output elf unless you are modifying the headers, if you mod them you must choose a new output file. to edit that line create a text file with the format as shown, fix the address so it is relative and add it to the file. select the file in elf mod edit codes tab and click set codes. This will then get the codes from the txt file provided and add them to the inputelf

[Lazy Bastard]

Right, I forgot about subtracting the starting address in my example.

But I still can't seem to mod anything. I made a .txt with

1
0x00000770 00000001

...chose the input elf, used the same file for the output elf, used Get Header Info to be sure the elf was read properly, selected the Edit File tab, and typed in the location of my text file [ c:\test.txt ], but Input Codes, Get Codes, and Set Codes all did nothing. I even used Hex Workshop's Fille Differencing engine to see if anything had been changed in the elf, but nada. Am I missing something?

[cYs Driver]

you need to prefix the data with 0x aswell

[Lazy Bastard]

Err...geh, this was just another typo in my example. I prefixed the value in my actual attempt. I tried another elf, but got the same results...

[cYs Driver]

mm i dont know what your doing because i get it working fine for me :S
il talk to you on aim some other time im going out all day

[Lazy Bastard]

Sounds good, man; thanks. If I manage to modify an ELF, will I get any indication that something happened, or will I have to check for file changes (eg, will I get a popup box saying I've successfully modded the elf)?

[Lazy Bastard]

Bleh, if I could either time my 'net appearances better to catch you before you're offline, or figure out what's going on, this tool would be really useful for me to figure out whether PS2Dis is disassembling ccheat.elf incorrectly/incompletely, or elfmaker is reassembling improperly...

Perhaps more detail will shine a light on what's going wrong. I name the txt "text.txt", and the elf is "unpacked.elf", in c:\. The ELF header loads fine, but I can't get Elf Modder to load the txt, nor can I get it to do anything if I manually add codes to the GUI's codes box, and mod the elf that way.

So I moved both files to the directory that's automatically in the "Input elf" box, "C:/cygwin/usr/local/ps2dev/ps2sdk/projects/find_syscall_vtbl/", but nothing changed. I've tried renaming text.txt to unpacked.txt, just in case that was relevant. I've tried with 1, 2, or 3 codes. I've tried different codes. I've tried different elfs. Can you attach (using the forum function, or your own if you prefer) an elf you've had success with (unmodded, so I might use it to test), with a proper txt? Has anyone else used Elf Modder successfully? I'm just wondering if it's possible we're all missing some essential part of Elf Modder.

[cYs Driver]

right that original directory was supposed to be removed from it, i had that there for the purposes of speeding up testing because all my elfs were there so ignor that...
at the moment the main text box in the GUI does nothing :S just was planned for the future. But hopefully il catch you this time on aim

[Lazy Bastard]

Cool. I'm currently at work, and most chat protocols are decently blocked. I could set up an SSH tunneling system of sorts, if I wasn't too lazy...I'll be home around 6PM Central Time.

[cYs Driver]

mm any change of giving me that in GMT lol
