I see. Got the 2x+1 4 bytes search to work for non-gold resources except tech tree. One interesting thing i saw is if you hover over your different saves when trying to load a game all the resources change value except the tech tree scrolls. I'm suspecting the display value to be a derivative of your current faction level and thus searching for it does nothing
Hmm interesting. On that note, trying to gain faction level doesnt really work, it feels like exp/cp is coded obtusely in a deliberate manner.
In other news, you can change item numbers, you have items that boost certain stats, exp, cp, etc. The downside is you do have to have these items in the first place to perform search. Maybe someone can do a table on these values later. This in addition with resource search leave tech upgrade the only value we can't modify....for now.
I think you can use this to add rpgm game value type so you can search directly for rpgm game no need to do calculation anymore

Target Turns always 1 (missions track how many turns you take to win, so if you can lock that at 1, you'll always succeed with that challenge)
If possible "Always Move". Most units automatically end turn after attacking. But Cavalry get to move after an attack. If you could make all units able to move at any time, that would be awesome.
Also, being able to edit unit stats would be great if there's a way to do that.

I'm sorry but how do you add this code into CE? That is indeed helpful since we don't have to add the *2+1 to our values
Thanks for sharing!
Edited:
Oh nvm, I figured it out. For those who are curious/lost just like me:
1) Start Symphony of War & CE, then select the process
2) Right Click on the 'Value Type' on the Right side of CE (just below the Scan Type)
3) Select 'Define new custom type (Auto Assembler)'
4) Paste the code above
5) ???
6) Profit. The Value type will display 'RPG VX Type' if you have done it correctly.

A quick google search will show that this code is likely from Dark Byte himself (the maker of Cheat Engine). In the same post on the original CE forum, you can also find the instructions on how to add the type in, as someone posted above
That's interesting. Any one knows why do they store values in these formulas (is it for better performance or its the game engine?). I'm a starting data engineer so I'm not familiar with game development and i cant imagine why game values are obfuscated
It's not obfuscated. It's just how binary works. In fact, instead of doing value*2+1, you can also switch CheatEngine to "Binary" and search for the value (without doing the multiplication and adding 1). note how alignment converts to "1" below. RPG Maker doesn't actually store it in a fixed 1/2/4 bytes space.
I tried just about every save editor I could find that is supposed to work with rvdata2 files for the saves and couldn't get any of 'em to work... So, If ya find one that actually works right shoot us a link!
Also for anyone curious, saves are in Users\Name\AppData\Roaming\Nephilim, at least for me.
To be able to use save editors or save edit online, you need to un-gzip the rvdata2 file first. It's gzipped. (not zip, gzip). You can use 7zip to do that. Then, add in the .rvdata2 extension to the raw file and you have the save file ready for editors. The raw file should be about 1 Mb in size while the gzipped is about 100-200 kB only.

Excellent tip! Indeed the gzip does the trick, though no editor seems to be able to read anything useful from the file.

After following your steps, I managed to edit the raw file using [Link]. However, I'm unable to load the save file. Do I need to gzip it again and convert back into rvdata2. I tried doing that with 7zip but it just ends up being a .gz file.

Did it give you anything useful beyond just a few unknown variables?

You need to use this: [Link]
Coupled with extracting some of the rvdata2 from the Game.rgss3a file in the game directory with the help of this tool: [Link] (items.rvdata2, weapons.rvdata2, etc ...)
It's a bit more effort from there to actually understand how they store the data (based on using hex editor to see how the save editor changed what value and then finding out the real value in there), I'm still fiddling around.
Yes you need to remove the extension, gzip it back, and change the .gz extension to rvdata2
It's best if you just use hexeditor to find for the values. Do two identical save. change value you want to change in one. then look at the difference between the two saves.
I'm not sure what I'm doing wrong. I can find gold by doing <value> x2 +1 under a 4byte search, and by exact value as a binary search. The problem is if I try to change the value under the 4byte search, the game crashes. When I change the value under binary, gold changes to a random value (I.E. changing gold to 9999 in CE changes gold to 1807 in-game no matter what value it's at). I'm not a programmer and have basic knowledge of CE. If someone can explain to me in the simplest of terms how to change gold correctly, I would greatly appreciate it.
