Scanning
MemREs Memory Scanner works like any other memory scanner available. The concept is to locate a value within memory. MemREs memory scanner comes with a variety of options including;
Value Types:
- Byte
- 2 Bytes
- 4 Bytes
- 8 Bytes
- Float
- and Double
Some key notes on Value Types are;
- Byte (8 bits) can be both signed and unsigned whole number ranging from -128 to 127 (signed) and 0 to 255 (unsigned).
- 2 Bytes (16 bits)(Short) can be both signed and unsigned whole number ranging from -32,768 to 32,767 (signed) and 0 to 65,535 (unsigned).
- 4 bytes (32 bits)(Int) can be both signed and unsigned whole number ranging from -2,147,483,648 to 2,147,483,647 (signed) and 0 to 4,294,967,295 (unsigned)
- 8 bytes (64 bits)(Long) can be both signed and unsigned whole number ranging from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 (signed) and 0 to 18,446,744,073,709,551,615 (unsigned)
- Float (4 bytes (32 bits)) is a real number with an approximate precision of 7 decimal digits with a minimum positive value of ~1.4 × 10⁻⁴⁵ and a max value of ~3.4 × 10³⁸
- Double (8 bytes (64 bits)) is a real number with an approximate precision of 5-17 decimal digits with a minimum positive value of ~4.9 × 10⁻³²⁴ and a max value of ~1.8 × 10³⁰⁸
Scan Options:
- Scan the Exact Value
- Scan a Value that's Bigger Than
- Scan a Value that's Smaller Than
- Scan for an Increased Value
- Scan for an Decreased Value
- Scan for a Changed Value
- Scan for a Unchanged Value
- And scan for an Unknown Initial Value
Some key notes on the Scan Options are;
- Scanning for an "Exact Value" must have a whole or real number inside the Values text box. i.e. 10 or 10.01.
- Scanning for a Value that's "Bigger Than" must have a whole or real number inside the Values text box. This value is expected to be greater than the whole or real number inside entered in the Values text box.
- Scanning for a Value that's "Smaller Than" must have a whole or real number inside the Values text box. This value is expected to be less than the whole or real number inside entered in the Values text box.
- Scanning for an "Increased Value" requires no whole or real number to be placed inside the Values text box. This is an assumption the number has increased from the last value that was scanned.
- Scanning for a "Decreased Value" requires no whole or real number to be placed inside the Values text box. This is an assumption the number has decreased from the last value that was scanned.
- Scanning for a "Changed Value" requires no whole or real number to be placed inside the Values text box. This is an assumption the number has increased or decreased from the last value that was scanned.
- Scanning for an "Unchanged Value" requires no whole or real number to be placed inside the Values text box. This is an assumption the number has not increased nor decreased from the last value that was scanned.
- Scanning for a "Unknown Initial Value" requires no whole or real number to be placed inside the Values text box, and can only be triggered on the first scan (Initial). This is an assumption the number is unknown.
Each scan option can be mixed and matched excluding the "Unknown Initial Value", as this is an initial scan type.
Value types can be changed between each scan and will reflect the current results value types between scans.
Scanning Tutorial
Below is a brief tutorial on how to complete a scan with MemRE.
Load the game and MemRE. In this demo I'll be using "Cinemaster Cinema Simulator"
Once loaded, attach (or inject) to the game. A window will prompt asking you to select the process.
Double click the process name, then verify you successfully attached (or injected) to the game.
Get into the gameplay so the values will fully populate in memory, then locate the value you would like to search. In this demo, we are targeting Money. Take note money is currently "9,999.00" right now. Because the value has a decimal, we know it's a real number (refer above if confused on value types), so it's either a float or double. I know it's a double, so I will select the correct value type, and enter the current value to be scanned, then press "First Scan".
As you can see, we have results in the Scan Results box and its showing 137 values out of 137. If you get more, and your value isn't changing, you can press "Next Scan" a few times to narrow down the results some.
To narrow the results down more, we will spend some money in the game so we can search for a new value. As you can see, i spent a single dollar, and now we have a value of 9,998.00
Now we can proceed by updating the new value in MemRE and press our "Next Scan" to further narrow down the results. As you can see, we are left with just one result.
Let’s double-click the results address, and MemRE will add it to our Table List and then we can verify our address by changing our money value back to 9,999.00. Double click the value that was added to the Table List..
While we are here, lets give it a name by double-clicking on the Description of our entry and giving it a name.
