The item list should be populated with the game's kernel; if you open the tool and click Settings (at the top) then Configuration, you should be see some addresses which point the tool toward the game's files; it can then use these files to show things like field models, item names, etc.
Omnislash is item ID 87.

Kimera: 3D Model Editor/ViewerThere is a tool to view/edit 3D Models but there's some steps involved and it's trickier to get running than the Wall Market tool. I'm a little hazy on the steps, but it'll involve installing some dependencies using the command line (administrator version).
First, the tool thread:
http://forums.qhimm.com/index.php?topic=4194.0Next, download and install Visual Basic Power Packs 3.0 if you don't already have it; this can help with getting old visual basic tools to run, like Wall Market.
For Kimera, you'll need to register some dependency files to get it working, specifically: MSCOMCT2.OCX, MSSTDFMT.DLL, msvbvm60.dll, and COMDLG32.OCX. If these aren't in the Kimera download, then I can get them to you instead; some sites provide old files like these but exercise caution about downloading such files from unknown sources.
I've only installed these via Windows 7, but a guide going through different OS can be found here:
http://www.ctimls.com/Support/KB/How%20To/Register_dll.htmOnce you've got the files, drop a copy of each into the Kimera tool folder. Next, go into the folder called Windows on your C drive and go to sysWOW64 folder. We're going to drop another copy of the four files into here, registering them via CMD one at a time. So drop those four files into this sysWOW64 folder.
Click Start and in the search bar type cmd; you'll see cmd appear above in search results; right-click this and select 'run as administrator'. On the command line, type:
cd\Windows\sysWOW64
and then press Enter. This gets us to the directory address where we're going to register our four files to the system.
Next, type:
regSvr32{filename.extension}
and press enter.
A success message of some sort should appear. Do this for each of the four files listed above. What this does is, it takes 32bit dependencies and gets them registered with the PC so that the tool can make use of them when running. These files used to be part of the system, but changes to the .NET Framework meant that old files got ditched which leaves older tools high and dry.

ULGP: .lgp Archive ManagerWhile that should get Kimera working, you'll need to take some steps to actually view models as FF7 has the 3D models tied up in archives with a .lgp format. We use a tool like Luksy's ULGP tool to decompile these archives into their individual files:
http://forums.qhimm.com/index.php?topic=12831.0When an archive has been decompiled, you can then open the models inside using their 'master' file (.hrc extension for field models from char.lgp, or files ending in 'AA' for battle models from battle.lgp; note that battle model files have no visible file extension). You can also open individual model parts too.
When edits have been made, we recompile the archive using ULGP again and it (should) be ready to go.
