Description

Virtual Script Machine Instructions (VSMX) file

Used on:

History:

Rcomage: 

does also have a VSMX decompile option (rcomage vsmxdec --decompile) 

but it's very buggy and usually doesn't work right (Try hex editing the version? (at 0x4) 

from 0x20000 to 0x10000.).

File Layout

(section naming need to be wikifyed): 

VSMX header
Compiled code/instructions
Data/String constants
(method) name table/Object property
global symbols/Variable/function names

Compiled instructions

  • Instructions length: 8 bytes

Instructions format should be wikifyed.

Arithmetic Operators

May be move later to PlayStation_JavaScript or make it as template

Arithmetic operators are used to perform arithmetic between variables and/or values.

OpCode (VSMX) Mnemonics (VSMX) Syntax (PSJS) Description:
0x02 ADD + Addition
0x03 SUB - Subtraction
0x04 MUL * Multiplication
0x05 DIV / Division
0x06 MOD % Modulus (division remainder)
0x0A INC ++ Increment
0x0B DEC -- Decrement

Bitwise Operators

Bit operators work on 32 bits numbers.

Any numeric operand in the operation is converted into a 32 bit number.

OpCode (VSMX) Mnemonics (VSMX) Syntax (PSJS) Description:
0x19 BIT_AND & AND
0x1B BIT_OR | OR
0x1C BIT_NOT ~ NOT
0x1A BIT_XOR ^ XOR
0x1D LSHIFT << Left Shift
0x1E S_RSHIFT >> Right Shift

Compare Operators

Comparison and Logical operators are used to test for true or false.

Comparison operators are used in logical statements to determine equality or difference between variables or values.

OpCode (VSMX) Mnemonics (VSMX) Syntax (PSJS) Description:
0x0E CMPEQ == Equality
0x10 CMPSEQ === Strict Equal value and equal type
0x0F CMPNEQ != Inequality
0x11 CMPSNEQ !== Strict not equal value or not equal type
0x15 CMPGT > Greater Than
0x14 CMPGE >= Greater Than or Equal To
0x12 CMPLT < Less Than
0x13 CMPLE <= Less Than or Equal To

Logical Operators

Comparison and Logical operators are used to test for true or false.

Logical operators are used to determine the logic between variables or values.
