so i have this arduino code, it works fine, but i think theres something wrong with my processing code, help is appreciated!

arduino code
1. const int latch = 2;
  const int clock = 3;
  const int data = 4;
  
  #define latchlow digitalWrite(latch, LOW)
  #define latchhigh digitalWrite(latch, HIGH)
  #define clocklow digitalWrite(clock, LOW)
  #define clockhigh digitalWrite(clock, HIGH)
  #define dataread digitalRead(data)
  #define wait delayMicroseconds(200)
  
  byte output;
  
  void setup()
  {
      Serial.begin(9600);
          while (! Serial ) { }
      pinMode(latch, OUTPUT);
          pinMode(clock, OUTPUT);
          pinMode(data, INPUT);
  }
  
  void loop()
  {
  output = 0;
  ReadNESjoy();
  // Serial.write(output);
  Serial.println ((unsigned int)output);
  }
  
  void ReadNESjoy()
  {
  latchlow;
  clocklow;
  latchhigh;
  wait;
  latchlow;
  for (int i = 0; i < 8; i++) {
       clockhigh;
       wait;
       output += dataread * (1 << i);
       clocklow;
       wait;
  }
  }
heres the processing code
1. import processing.serial.*;
  import java.awt.*;
  
  Serial arduino;
  
  Robot VKey;
  
  PImage bgImage;
  
  char recvout;
  char prevout;
  char deltaout;
  
  void setup() {
  size(434,180);
  frameRate(30);
  println(Serial.list());
  arduino = new Serial(this, Serial.list()[0], 9600); // ATTENTION!!!
  bgImage = loadImage("NEScontroller.jpg");
  try
  {
  VKey = new Robot();
  }
  catch(AWTException a){}
  prevout = 0;
  }
  
  void draw() {
  if (bgImage != null) { background(bgImage); }
  fill(255, 255, 0);
  serialRead();
  deltaout = (char)((int)recvout ^ (int)prevout);
  emulateKeyboard();
  prevout = recvout;
  }
  
  void serialRead() {
  while (arduino.available() > 0) {
  recvout = arduino.readChar();
  }
  }
  
  void emulateKeyboard() {
  if ((deltaout & 1 ) == 1 ) { if ((recvout & 1 ) == 1 ) {VKey.keyPress(KeyEvent.VK_L);} else {VKey.keyRelease(KeyEvent.VK_L);}}
  if ((deltaout & 2 ) == 2 ) { if ((recvout & 2 ) == 2 ) {VKey.keyPress(KeyEvent.VK_K);} else {VKey.keyRelease(KeyEvent.VK_K);}}
  if ((deltaout & 4 ) == 4 ) { if ((recvout & 4 ) == 4 ) {VKey.keyPress(KeyEvent.VK_G);} else {VKey.keyRelease(KeyEvent.VK_G);}}
  if ((deltaout & 8 ) == 8 ) { if ((recvout & 8 ) == 8 ) {VKey.keyPress(KeyEvent.VK_H);} else {VKey.keyRelease(KeyEvent.VK_H);}}
  if ((deltaout & 16 ) == 16 ) { if ((recvout & 16 ) == 16 ) {VKey.keyPress(KeyEvent.VK_W);} else {VKey.keyRelease(KeyEvent.VK_W);}}
  if ((deltaout & 32 ) == 32 ) { if ((recvout & 32 ) == 32 ) {VKey.keyPress(KeyEvent.VK_S);} else {VKey.keyRelease(KeyEvent.VK_S);}}
  if ((deltaout & 64 ) == 64 ) { if ((recvout & 64 ) == 64 ) {VKey.keyPress(KeyEvent.VK_A);} else {VKey.keyRelease(KeyEvent.VK_A);}}
  if ((deltaout & 128) == 128) { if ((recvout & 128) == 128) {VKey.keyPress(KeyEvent.VK_D);} else {VKey.keyRelease(KeyEvent.VK_D);}}
  }
im running on 1.5.1
