I found my value, float 0.99, a bunch of copies of it.
When I change values in memory viewer, it works.
When I change values using "Value" function from the address list, it always changes the value from 0.99 to ??. What is going on?

I opened the process.
I looked for the float value 0.99. I know that the game speed parameter default value for my game is 0.99 in float. I am new to Cheat Engine so I decided to try doing something I already know how how to do in PPSSPP. I added some values to the address list. I double-clicked on the value and entered a new value. This changed that value (and some others) to ??.

Ideas? What's going on?

The screenshot shows some values I haven't changed yet and some that I attempted to change already.

You're trying to write to an area of memory that is fenced off and protected.
First thing is to make sure CE is not hooked to anything.
Then go to table, go to Table Lua Script, and copy and paste this code in:

Code:

dbk_initialize()

openProcess([[cheatengine-x86_64.exe]])
reinitializeSymbolhandler()

autoAssemble([[
alloc(NewVirtualProtectEx,256, VirtualProtectEx )
alloc(OriginalVirtualProtectEx, 8, VirtualProtectEx)
registersymbol(NewVirtualProtectEx)
registersymbol(OriginalVirtualProtectEx)
label(notself)
NewVirtualProtectEx:
cmp ecx,ffffffff
jne short notself


jmp [OriginalVirtualProtectEx]


notself:
xor rax,rax
ret

]])

s=generateAPIHookScript("VirtualProtectEx", "NewVirtualProtectEx", "OriginalVirtualProtectEx")

--stupid bug in generateAPIHookScript forgets the alloc originalcall0
s=[[alloc(originalcall0, 64, VirtualProtectEx)
]]..s

autoAssemble(s)

dbk_useKernelmodeOpenProcess()
dbk_useKernelmodeProcessMemoryAccess()

--dbk_writesIgnoreWriteProtection(true)

After the code runs, you'll see a flashing box in the top corner of your screen that says either dbk64 is loaded or dbk32 is loaded. Now hook CE to the program you're hacking. Try changing the value and it should stay where it is. if this doesn'the work, you need to do two things. First, make sure you're on Cheat Engine 6.5.1 Then, take the two "--" out of dbk_writeIgnoreWriteProtection (true)
Dark Byte told me how to do this yesterday so 100% credit goes to him.
