Thank you for viewing. The item is Mike Tyson's Punch-Out!!. It worked a few months ago, but there were several bugs and errors, so I'm selling it as junk. I felt like I could play it normally if the cartridge was inserted correctly. Due to the above, I am selling it as junk. Mike Tyson's Punch-Out!!, made in 1987, is a game cartridge of the HVC-PT model. - Product Name: Mike Tyson's Punch-Out!! - Model: HVC-PT - Year of Manufacture: 1987 - Manufacturer: Nintendo Thank you for viewing.
