// Partial Action Replay code system implementation.
// Will never be able to support some AR codes - specifically those that patch the running
// Action Replay engine itself - yes they do exist!!!
// Action Replay actually is a small virtual machine with a limited number of commands.
// It probably is Turning complete - but what does that matter when AR codes can write
// actual PowerPC code...
// -----------------------------------------------------------------------------------------

// -------------------------------------------------------------------------------------------------------------
// Codes Types:
// (Unconditonal) Normal Codes (0): this one has subtypes inside
// (Conditional) Normal Codes (1 - 7): these just compare values and set the line skip info
// Zero Codes: any code with no address.  These codes are used to do special operations like memory copy, etc
