It took me a little time to get used to the controls, and I was surprised when I managed to win some bouts, but at the end of the video, I got to a "Load tape..." section, and then it all ground to a halt. How do you deal with that, please?
The tape needs "rewinding" to find the other character's data... I don't know which emulator you're using, but on Spectaculator there is a "stop at end of tape" option which needs disabling to allow the tape to loop indefinitely. So you'll need to find your emulators similar option or "rewind" button. Hope that info can help you, and if so please reply here with details so I can add the info for other players if you find it! Many thanks 🙂
