I am using batocera 3.5 and want to use a real wiimote as a classic handle to play retro games. Connect to the system via Bluetooth. After successful matching, set the wiimote mode to joystick in the handle setting option. In ES, wiimote has changed to SIDE mode, and the direction keys, 1, 2, -, and+have all changed to vintage handle mode. However, when entering the MAME game, I found that although RetroArch called the SIDE mode of ES, it also called the vertical wiimote direction key as the four keys on the keyboard, and the simulator recognized the wiimote as the direction key in the vertical direction in the game options menu; At this point, in the RetroArch menu invoked with the hotkey, the up and down selection of the menu using wiimote is still in the vertical direction. Because the default direction key of the MAME 2010 simulator P1 is to invoke the keyboard direction key, key position conflicts occur in the game. In the game, wiimote is used to control the direction. The actual game character presses both the two key positions of the wiimote and the vertical wiimote in side mode to control the direction (45 degrees from the desired direction). If you use the 360 handle to control P1 and the wiimote to control P2, the side mode wiimote direction control will still control the P1 direction (vertical direction). Does the big god know how to solve this problem?
