Arcade Game: Karate Champ (1984 Data East)
This game inspired countless and endless number of fighting games especially street fighter and neo geo fighting games, Without this, fighting games in the arcades would have never existed.
There are 2 different versions of this game. Stadium and Street. The Stadium version comes first and gameplay starts at 2:11. Street Version (known as the Vs version) begins at 30:55 and gameplay starts at 34:06.
No cheats used. Only savestates used.
Note: The Stadium version (the original) is endless after beating the last level 30 times and shows no sign of stopping. After all levels are shown, I quit. The street version (known as Vs version) which has 12 different backgrounds in corresponding 12 levels, was thought to be endless which indeed, does have an ending. On this version, the levels only repeat themselves once, which means you have to play those levels twice in order to get to the ending. Once you beaten all of the repeated levels once, the ending is shown and the game is over. I also including the ending from the Japanese version which has the same ending but different fonts and uses Japanese characters.
