This copy of Kaiketsu works, but it’s a little messed up. When you turn it on, the graphics show vertical lines throughout the screen. I cleaned the pins like 10 times but I just couldn’t get it to play right.
If you’re an expert game fixer, maybe you can get this to work properly!
Same as the photos.
Japanese version fits in a Famicom, or an NES with a 60-72 pin adapter.
