Nes has been revived on your computer. With Nesticle you can play old nes games on your PC. I am only advetising Super Tecmo Bowl because it is the best nintendo game of all time. Nesticle has the options to play net games. What I would like to do is create a Tecmo Super Bowl internet league. That way we could find the best Tecmo Bowl player in the world. It will probably be me. 
     Below are a couple screenshots of Tecmo Super Bowl showing most of the options. Also I have posted the ROM and Nesticle.

Teams
      This is a screen shot of all the teams you can choose from. All the teams are from the 1990 NFL season. The best teams in the game are Buffalo and San Francisco, because they have the best passing and fairly good rushing. But all the teams have their high points.
     In Super Tecmo Bowl you are allowed to change your play book which is a vast improvement over the original Tecmo Bowl. Basicly you can pick four run plays and four pass plays out of about eighty plays. Your play book usually determines weather you win or not.

Players
      This is a screen shot of a players stats. This tells you how fast they are, how well they hit, and how well they control the ball. Also it shows you some other information. Different players have different catagories though. This is a tight end, he is in excellent condition so you might want to put him in as your running back instead of your tight end. You'll get the most out of him that way.
     When you finish a game you will be shown the offensive stats. If you are playing a season game it will show you all other categories in the NFL Leader board.
Standings
     Below are newer versions of Tecmo Bowl for the Genesis and Genesis Emulators. Whoopie! I recommend Genecyst which is made by the same people as Nesticle. KGen is for people who are having trouble with compatibilyity with Genecyst. Enjoy.

     Also availible is Tecmo Bowl for the Genesis/Mega Drive. Has all the above features plus many more and better graphics. You know have 16 plays to choose from and four different defensive formations! Also all the team data is relevant for its time.
     In this version you can also create your own players for any team. Also the expansion teams are here and more comprehensive  stats. You can now see negative stats. Over all it is better except Genecyst and KGen don't allow internet play like the NES version.
