Hi @perceval, always a pleasure to have you around.... To be honest even though "Mike Tyson's Punch-Out" was a very well known title on the NES, I never got to play it, I find it strange that in all my life with retro games, I never knew about this title.

As for "Mike Tyson Boxing", I can recommend it with my eyes closed, when you decide to play it, I advise you to practice a little to familiarize yourself with the controls, and then you go to the world mode, I assure you that you will have a good time, it's fun when you insult each other in the newspapers of the week, I hope you try it bro!
Thanks for your time, greetings!
