A vintage game "Karateka"

A rhetorical question: if you have never played Karateka it’s worth doing it. You can google for the karateka.dsk.gz file and load it into the AppleWin emulator.

There is a DOS version, but, unfortunately, the gameplay was slightly changed. In the Apple’s version the opponents inside the house never approach you first. There was a trick: a little step towards and immediately step back. This was the only way to force them to attack you. Then you can low-kick them. In the DOS version they always attack first, so just low-kick.

But for the DOS version there is a magic patch allowing to speedrun the game.

P.S. Unfortunately, the sources of this spectacular game are still closed.
