 usually, size 0 = 8-bit, size 1 = 16-bit, size 2 = 32-bit. For some codes, Size 3 = Floating point single precision.
 
+#### Code Generation Python Script
+
+You can use the below Python code (requires Python 3.6 or higher) to quickly generate an address for a normal Action Replay code.
+
+```
+typeVal = int(input("Enter Type Number: "))
+subtypeVal = int(input("Enter Subtype Number: "))
+sizeVal = int(input("Enter Size Number: "))
+address = int(input("Enter memory address without base 0x8000000 value in format `0x1234567`: "), 16)
+
+result = ((subtypeVal) << 30) + ((typeVal) << 27) + ((sizeVal) << 25) + address
+print('{0:0{1}X}'.format(result, 8))
