how can I get the value of I/O in the Dreamcast?

[developer]

Just a little example

First initialize input device, for instance joystick

PHP код:

maple_device_t* joy = maple_enum_type(0, MAPLE_FUNC_CONTROLLER); 


Then, poll joy's buttons state

PHP код:

cont_state_t *joy_state = (cont_state_t *)maple_dev_status(joy);
if (joy_state->joyx != 0 || joy_state->joyy != 0)
{
    Ball->Move(joy_state->joyx, joy_state->joyy);
}
