 Operations take either 0 or 1 parameter. The ones that take a parameter, it can be either a int8, int16 or int32.
 
-The binary of the opcode is: XXYY.YYYY, where XX defines the parameter type, and YY.YYYY is the instruction. For the XX values:
+Instructions follow this logic:
+
+00 ~ 9F : no parameter
+A0 ~ BF : int8 (1 byte)
+C0 ~ DF : int16 (2 bytes)
+E0 ~ FF : int32 (4 bytes)
+
+The operations of 1, 2 and 4 bytes are always interchangeable by adding/subtracting 0x20.
