Function Documentation

◆ pce_joypad_next()

uint8_t pce_joypad_next ( void )

Read the next joypad controller's pressed buttons.

If a multitap is to be used, one should use this function for all controllers after the first one (which should use pce_joypad_read instead).

Returns: uint8_t Buttons currently pressed.

◆ pce_joypad_read()

uint8_t pce_joypad_read ( void )

Read the first joypad controller's pressed buttons.

Returns: uint8_t Buttons currently pressed.

◆ pce_joypad_wr()

uint8_t pce_joypad_wr ( uint8_t value )

Write a value to the joypad I/O port, then read the result.

Parameters

value The value to write.

Returns: uint8_t The value read.
