(adsbygoogle = window.adsbygoogle || []).push({}); You need two things:

-Hashtab
-BruteCRC32

Get HashTab from [You must login or register to view this content.] and right click an original file that is unedited and get its CRC32 hash, write it down / copy and paste it into notepad.

Edit the file with all your DVARS, save it, and look at the new hash, it's different. That's where BruteCRC32 comes in.
(The DVARS are all in the Console MP log. You must login or register to view this content.)

Download BruteCRC32 from [You must login or register to view this content. and open it, and then point it to the file you edited, and force it to have the CRC that you copy and pasted / wrote down earlier.

The program will appear to freeze, but it's just doing its job. Leave it alone, and you have an "original" save to use!

If anything needs to be cleared up, ask.

Example, let's say I was just editing GPAD0_MP.

Using Hashtab I see the original CRC hash.
I then edit it, and get a different one below:

Then I use BruteCRC32 to "force" the new hash to become the old one, like it was never edited. See?

I don't understand how to put the dvars in. I opened the file in a hex program and notepad and can't find any compress=$mapname or whatever. Can I just go to the bottom of the svg in notepad and paste the codes in and will it work?

For those asking for the dvars list. Here's a notepad file of all of them. It's not formatted, so you'll have to read through to find what you're looking for.

No clue if these will work on console, as these are from PC. Anyway, worth checking out IMO.

it's safe, I looked at it already.

EDIT: NVM, I went back and looked further, looks like it might be for the X360, note near the bottom it has these:
xblive_hostingprivateparty "0"
[ 702149] xblive_loggedin "0"
[ 702149] R xblive_playEvenIfDown "0"
[ 702149] xblive_privatematch "0"

I'm going through it now to clean it up for you guys. I will link to the download once I'm done... yea, I'm at work and doing a remote access to my PC so it's going to take some time.
