[Off-topic] dbzfanatic:
Actually I thought I mentioned the file compare method on here already :P. That's a method, also the most common, to find the values you need if the straight "search for them" method doesn't work. If you could read team names at all that means there's no encryption, I posted a bit more info about that in a previous post with an example of plain-text and basic encryption. I'm glad this is what you were looking for. Ok on to the next topic.

How to Hex​

Most people think hexing is a really daunting task. It isn't. I actually already explained most of what you need to know in post #9 but I'll go over the basics again. Once you open a file in your hex editor you should see something like this on one side (the left usually)

0D 0A 3C 21 2D 2D 20 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 0D 0A 54 68 69 73 20 63 6F 64 65 20 73 68 6F 75 6C 64 20 62 65 20 70 6C 61 63 65 64 20 69 6E 20 74 68 65 20 68 65 61 64 65 72 20 6F 72 20 69 6E 20 61 20 43 53 53 20 66 69 6C 65 2E 0D 0A 49 74 20 63 61 6E 20 62 65 20 6D 6F 64 69 66 69 65 64 20 74 6F 20 6D 61 74 63 68 20 74 68 65 20 61 70 70 65 61 72 61 6E 63 65 20 6F 66 20 74 68 65 20 72 65 73 74 20 6F 66 20 74 68 65 20 73 69 74 65 2E 0D 0A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A 2A

and on the other you should see what that represents, in this case it's some html

If the right side is easily readable like it is here, there's no encryption. If it looks something like

A2e76f!_ #4jf9@ ......... emishUGLhvEEas~_

then it's probably encrypted. You need to look carefully though since some things may seem encrypted at first glance but really aren't like

sysSettings1sysSettings2sysSettings3.........weapon_023464........63

In this example you can see that system settings 1, 2, and 3 are unlocked and the player has 99 (which is 63 in hex ;) ) of the item "weapon_023464". They won't always be this easy to read but this shows my point quite well. If we wanted to unlock system setting 4 in this example the first thing to try would be to change the right side (the "readable" side) to

sysSettings1sysSettings2sysSettings3sysSettings4.........weapon_023464........63

rehash/resign, load it back and see if it works. If it doesn't then the next method to try would be to find a savegame that already has it unlocked and compare the two. Let's say the save with it unlocked looks like this

sysSettings1sysSettings2sysSettings3sysSettings_04.........weapon_023593........03

We can clearly see that they changed the naming on menu 4. So all we need to do is change our modified file to

sysSettings1sysSettings2sysSettings3sysSettings_04.........weapon_023464........63

rehash/resign and load and all should be well.

"Oh but that's easy, what if the file is encrypted then what do I do?" I know some of you are thinking this. Well that's where the file-compare method comes into play again. Say we have 2 saves that look like this.

We can see some similarities and some differences. Notice they both have "01234567890123456789" in them in the same place and they both end with "!....". The first 8 letters are different though and some of the middle is different. A safe assumption is usually if something changes at the very beginning of the file or at the very end it's a potential checksum. I'll explain more about those later. Say we only changed our stat for gold in the game between the two saves we have. Since we think the first change is a checksum that means the second change must be our gold number. Now we have no idea what the encryption method is at the moment but we do know how much our gold was and is and where in the file it's saved now. So we keep that information handy and build up our gold to an ungodly amount through work or cheats, save, and open the file. It now looks like this.

We can clearly see that the same two places have changed. First thing to try (shot in the dark) is take the area we think is gold and put it in our first save. That would make it look like this

We ignore the possible checksum for now, rehash/resign and load it up to see if it works. To our shock it does! Our gold has jumped but everything else is exactly the same as the first save so we think to ourselves "what else could have changed between those two saves I had first?" The answer is simple. The time. The first few bytes of our file are our gameplay time. There are games that use checksums and if the edited save doesn't load up then that game probably does. This example was just to get you into basic hexing, not bypassing game security. If this made your head explode, please get a bucket and try again :P. It gets easier, I promise. Just re-read this a few times, eventually it will "click" and you'll understand.

Edit: Just in case my way was a bit difficult to understand I found another explanation posted by Emerald Lance, it's the same info just worded a bit differently. Maybe you can understand this one if you can't understand mine.
