This item is from the second owner. It was purchased for 16,000 yen at the time. It was used as a slot controller to enhance the immersive experience when playing on 777 Town (Samita). Operation has been confirmed. Before listing, I confirmed that it works without any problems on 777 Town. The button lamps light up, and I have also confirmed that they work without any problems. ※MAX BET button always on → press to turn off → lever on → 3 buttons light up → button pressed turns off → releasing the third button turns on the MAX BET button, and this is repeated. I have prepared a 360-degree photo, so please check the condition before purchasing. Also, since I am an amateur, I will describe the content that the person who listed it at the time wrote below. 【Overview】This is a modification of a PlayStation pachislot controller to be recognized as a Windows USB keyboard (HID device). (It no longer works on PlayStation) It is possible to assign keyboard buttons to 12 buttons. (Settings can be changed with Windows software) It supports pachislot games that can be operated with a keyboard, such as Samita. The PRO was once sold by professionals, and many are in circulation, but I am proud that it is superior in functionality, such as the following lamp effects, button additions, and button settings. 【Ver.2.0】In this version, a circuit for LED control has been added for button lamp effects. This allows the MAX BET button and stop button to light up/turn off in a way that is similar to the actual machine, enhancing the game's progression. ※It is not linked with the app. Since the app does not send ON/OFF signals for the lamps to the controller, it is a "pseudo-link" that turns the lamps ON/OFF in accordance with button operations. Depending on the operation, there may be discrepancies with the app's effects, but in normal gameplay, it generally appears to be linked. A square button has been added so that it can be used for the CHANCE (PUSH) button. I tried playing on Samita. When combined with the screen size, you can play with a feeling close to the actual machine. I am not a professional or a pro, but a hobbyist, so the wiring is a bit rough, but I played for a little over an hour as a test, and I don't think there were any particular problems with the operation.
