Okay, so there is this game that won't let me change the value of the money. I found two values for the money. The first value updates the value visually, but is not the actual value. When changed to say... 8,888 the status says 8,888 until you try to buy something. Then it will say you don't have enough and shows that you actually have 5,402. The second value I found is for the actual amount of money in the game. When I try to change the second value, it just goes back to what it was and remains unchanged. When I try to update them both simultaneously, the money status value changes, but goes back down almost instantly to the original value. I think the game is protective because when I tried to find what wrote to the address, it gave me an error saying I couldn't place a debugger. I tried the prevent debugger detection but that just made CE nonresponsive. Not exactly sure how to get around this:/

Maybe needed info?
The values are 4bit
I changed the scan settings so I could scan for the values in Physical Memory process(this was necessary otherwise I couldn't find them)
It's an android app I am running through bluestacks on a super beefycomputer (it has worked with other apps, this one is just stubborn)

Please help me! also please only post if you can actually help. I don't want to sift through useless info and waste my time with ideas that come from wild guessing. Thanks!

Did you try unknown initial value scan with NEVER typing in what's shown on-screen, just use increased/decreased? Lots of games lie about their values for one reason or another (most legit ones).

I found both values by exact value scan. It was actually pretty easy finding the values once I adjusted the scan settings (so I could select physical memory process[pmp]). I know these two values must be the values I am searching for because pmp let's me scan everything, so the value couldn't be hidden. I also knew they were the values I wanted because both would change if I earned/spent money legitimately which made the values match.

What Rydian meant by hidden is that the value is encrypted.
Just because the value displays as "5" on screen, doesn't mean the game stores a "5" in memory.
The usual trick is to XOR the value against a mask and store that new value in memory.
Then, when the game wants to change the value or use it for display, it will XOR it with the same mask.
This converts the encrypted value back into the "5" that is needed for calculations/display.

If changing the values that you found does not have an effect in game, then you found the wrong addresses.
As Rydian stated, use the unknown initial value scan and increased/decreased rescans.
The value you find will look completely wrong, but changing it will affect the game.

Okay I will try this. If they went through the trouble of hiding the value, what if they change the way the value changes too? Ex: spend 100 but the actual value decreases by 1000. How could I find this out, that value is actually changing by the amount it says it is changing? What scan type would you recommend?

Again, unknown initial value and increased/decreased will find that.

It could also be that the value is in a different type than you scanned for, or the actual value is /10 or *10 or something (more common with currencies).

I made changes to coins balance in cheat engine but it doesnt change on app.

I have noticed when i tried changing the value of middle entry, it was reverting back to previous one and I had to close one of the window of app and then it let me change it in CE.
