psp 1000 joystick unable to configure in retropie

[ghost08]

hello, I am using a psp 1000 joystick in my pocket pi build. when I go to configure it in retropie however, it is not responding correctly. i am only able to register two out of the 4 directions, up and left. and when it registers it it's labeled as 0+ and 1+ for the keys, im not sure if thats important or not. here is the code that I borrowed to use as a template, all other buttons work. I dont know much about coding, could someone please help me out. Thanks in advance!

//Run with at least Serial & Joystick USB modes

typedef struct button
{
int pin;
int button;
} button_t;

void joystick_x(unsigned int value)
{
Joystick.X(value);
}

void joystick_y(unsigned int value)
{
Joystick.Y(value);
}

typedef struct joystick
{
int pin_x;
int pin_y;
void (*func_x)(unsigned int);
void (*func_y)(unsigned int);
} joystick_t;

//Buttons
button_t buttons[] = {
{0, 1}, //Y
{1, 2}, //B
{2, 3}, //A
{3, 4}, //X,
{A0, 14}, //DPAD_UP
{A1, 15}, //DPAD_DOWN
{A2, 16}, //DPAD_LEFT
{A3, 17}, //DPAD_RIGHT
{4, 5}, //LB
{5, 6}, //LT
{6, 7}, //RB
{7, 8}, //RT
{12, 13}, //MENU
{A8, 18}, //MUTE
{10, 11}, //VOL-
{11, 12}, //VOL+
{8, 9}, //SELECT
{9, 10} //START
};

int buttons_size = sizeof(buttons) / sizeof(button_t);

//Joysticks
joystick_t joysticks[] = {
{A0, A1, joystick_x, joystick_y} //Left analog
};

int joysticks_size = sizeof(joysticks) / sizeof(joystick_t);

int i;

void setup() {
Serial.begin(9600);

//Digital pins buttons
for (i = 0; i < buttons_size; i++)
{
pinMode(buttons.pin, INPUT_PULLUP);
}
}

void loop()
{
//Digital pins buttons
for (i = 0; i < buttons_size; i++)
{
if (digitalRead(buttons.pin) == LOW)
{
Joystick.button(buttons.button, 1);
}
else
{
Joystick.button(buttons.button, 0);
}
}

//Joysticks
for (i = 0; i < joysticks_size; i++)
{
joystick_t joy = joysticks;
joy.func_x(analogRead(joy.pin_x));
joy.func_y(analogRead(joy.pin_y));
}
}

just to be a little more specific, im using a Teensy LC and Arduino 1.8.9

Does anyone have any idea about this? Also, I can use the joystick in the menus but not in games. Why is this?
