mame模拟器添加按键实现

osdinput.c文件里面，主要是这样子设置的：

 input_device_item_add(devinfo, "Bt_B", &joy_buttons[i][0], ITEM_ID_BUTTON1, my_get_state);input_device_item_add(devinfo, "Bt_X", &joy_buttons[i][1], ITEM_ID_BUTTON2, my_get_state);input_device_item_add(devinfo, "Bt_A", &joy_buttons[i][2], ITEM_ID_BUTTON3, my_get_state);input_device_item_add(devinfo, "Bt_Y", &joy_buttons[i][3], ITEM_ID_BUTTON4, my_get_state);input_device_item_add(devinfo, "Bt_L", &joy_buttons[i][4], ITEM_ID_BUTTON5, my_get_state);input_device_item_add(devinfo, "Bt_R", &joy_buttons[i][5], ITEM_ID_BUTTON6, my_get_state);input_device_item_add(devinfo, "Coin", &joy_buttons[i][6], ITEM_ID_BUTTON7, my_get_state);input_device_item_add(devinfo, "Start", &joy_buttons[i][7], ITEM_ID_BUTTON8, my_get_state);input_device_item_add(devinfo, "X Axis", &joy_axis[i][0], ITEM_ID_XAXIS, my_axis_get_state);input_device_item_add(devinfo, "Y Axis", &joy_axis[i][1], ITEM_ID_YAXIS, my_axis_get_state);input_device_item_add(devinfo, "D-Pad Up", &joy_hats[i][0],(input_item_id)( ITEM_ID_HAT1UP+i*4), my_get_state);input_device_item_add(devinfo, "D-Pad Down", &joy_hats[i][1],(input_item_id)( ITEM_ID_HAT1DOWN+i*4), my_get_state);input_device_item_add(devinfo, "D-Pad Left", &joy_hats[i][2], (input_item_id)(ITEM_ID_HAT1LEFT+i*4), my_get_state);input_device_item_add(devinfo, "D-Pad Right", &joy_hats[i][3], (input_item_id)(ITEM_ID_HAT1RIGHT+i*4), my_get_state);

这里注册设备，然后对应的名字，以及这个对应的从哪个数组里面拿数值。

static INT32 my_get_state(void *device_internal, void *item_internal)
{UINT8 *keystate = (UINT8 *)item_internal;return *keystate;
}

这个方法，是模拟器内部调用，我们只需要改动前面的值就可以了。、
我们使用的地方：
droid_ios_poll_input
这里面，是上层的按钮按下，弹起，会将这里面的一些数组改，主要是按下：0x80，弹起0x0
通过这两个值，模拟器会得到一次按下，然后驱动模拟器内部运行。

void droid_ios_poll_input(running_machine *machine)
{    my_poll_ports(machine);long _pad_status = joystick_read(0);netplay_t *handle = netplay_get_handle();int netplay = handle->has_connection && handle->has_begun_game;if(mystate == STATE_NORMAL){keyboard_state[KEY_1] = 0;keyboard_state[KEY_2] = 0;if(myosd_exitGame || handle->state.ext & NP_EXIT || handle->peer_state.ext & NP_EXIT){if(netplay){if(myosd_in_menu){if(handle->state.ext & NP_EXIT || handle->peer_state.ext & NP_EXIT){keyboard_state[KEY_ESCAPE] = 0x80;myosd_ext_status &= ~ NP_EXIT;}else{myosd_ext_status |= NP_EXIT;}}else{handle->has_connection = 0;handle->has_begun_game = 0;keyboard_state[KEY_ESCAPE] = 0x80;}}else{handle->has_begun_game = 0;//ensure for auto disconnect keyboard_state[KEY_ESCAPE] = 0x80;}myosd_exitGame = 0;handle->state.ext &= ~ NP_EXIT;handle->peer_state.ext &= ~ NP_EXIT;}else{keyboard_state[KEY_ESCAPE] = 0;if(myosd_reset_filter==1){myosd_exitGame= 1;}}if(myosd_service && !myosd_in_menu && !netplay){keyboard_state[KEY_SERVICE] = 0x80;myosd_service = 0;}else{keyboard_state[KEY_SERVICE] = 0;}keyboard_state[KEY_LOAD] =  0;keyboard_state[KEY_SAVE] =  0;if(myosd_savestate || handle->state.ext & NP_SAVE || handle->peer_state.ext & NP_SAVE){if(netplay){if(handle->state.ext & NP_SAVE || handle->peer_state.ext & NP_SAVE){keyboard_state[KEY_SAVE] =  0x80;mystate = STATE_LOADSAVE;myosd_ext_status &= ~ NP_SAVE;}else{myosd_ext_status |= NP_SAVE;}}else{keyboard_state[KEY_SAVE] =  0x80;mystate = STATE_LOADSAVE;}handle->state.ext &= ~ NP_SAVE;handle->peer_state.ext &= ~ NP_SAVE;myosd_savestate = 0;myosd_fs_counter = 60 * 5;return;}if(myosd_loadstate || handle->state.ext & NP_LOAD || handle->peer_state.ext & NP_LOAD){if(netplay){if(handle->state.ext & NP_LOAD || handle->peer_state.ext & NP_LOAD){keyboard_state[KEY_LOAD] =  0x80;mystate = STATE_LOADSAVE;myosd_ext_status &= ~ NP_LOAD;}else{myosd_ext_status |= NP_LOAD;}}else{keyboard_state[KEY_LOAD] =  0x80;mystate = STATE_LOADSAVE;}handle->state.ext &= ~ NP_LOAD;handle->peer_state.ext &= ~ NP_LOAD;myosd_loadstate = 0;myosd_fs_counter = 60 * 5;return;}for(int i=0; i<4; i++){if(i!=0  && myosd_in_menu==1 && myosd_num_of_joys <=1)//to avoid mapping issues when pxasp1 is activebreak;_pad_status = joystick_read(i);if(i==0){if(!myosd_inGame && !myosd_in_menu){keyboard_state[KEY_PGUP] = ((_pad_status & MYOSD_LEFT) != 0) ?

}

我们改动主要是这里，配合着上层java，完成对打。同时这块还可以设置热键，组合键。
