I saw some topics asking how this was done...and it actually isn't very complicated so I wrote a small tutorial for anyone interested.

Needed:
    Xextool 5.2 (Xorloser)
    Xorloser's PPC Altivec plugin v1.6 for IDA v5.6
    IDA
    Hex editor
    Black Ops xex


1. Make sure you have xextool and the black ops xex in the same folder.

2. Shift and right click to "Open command window here"

3. Type the below command shown in the picture changing "blop.exe/blop.xex" to whatever you named your xex

4. You have now extracted the basefile from the xex and created an idc file used to analyze the basefile as code. Below is shown where to load in IDA

5. Drag your basefile (.exe) into IDA, this needs to be loaded as a binary using the PPC processor setting.

6. Use the addresses referenced by Xextool load your basefile.

7. Select OK. Then File >IDC file. Select the idc file created by Xextool. Select Yes analyze as code

8. Find the string for the Dvars that you want to change *those that have floats* and find the corresponding hex bytes in Hexview

9. Open your basefile in a hex editor search for the exact hex bytes then change them to your wanted values.

10. Now, open your xex *note the actual xex* in hex editor and search for where the executable actually begins, search for the exact ansi string "MZ" and replace your modded basefile *which starts with MZ* over the Xex

NEW: How to turn on the DVARS







1. Find the Dvar you want to switch to on

2. Change the Hex byte at the end of the below to 01 from 00

3. Here is the same as above except for "sustain_ammo"

[spoil]Then load your xex on your Jtag and your replaced values should be reflected in the game...the above example will make your player have 0 friction *slides around the map* although with changing different floats comes different effe
