I am selling two dedicated controllers, purchased new at the time, that I used for double play. They worked fine a few years ago, but I don't have an environment to test them now, so I'm selling them as is. The buttons would often get stuck in the original product, which was inconvenient, so I made some personal modifications. They are in good condition, but please understand the above. By the way, although not connected, the buttons seem to be working well when pressed. KONAMI beatmania IIDX DX controller, 8-button specification, black and blue design. - Brand: KONAMI - Model: beatmania IIDX DX - Type: Controller - Number of buttons: 8 buttons - Color: Black/Blue - Bottom color: Blue Thank you for viewing.
