Double Dragon II: The Revenge

The Good
It mostly has everything that the arcade version has to offer.

It has the 2 player co-op mode!

There is simultaneous music and sound effects during gameplay, plus some digitized sound samples happen occasionally.

The Bad
One button Atari-style joystick controls. Not very comfortable, but manageable.

It's a bit slow, it feels like you are walking in mud all the time.

The graphics looks ugly, in that dirty/crusty way that rushed C64 ports often look. But it works, and the gameplay is surprisingly intact!

The Bottom Line
Unlike the port of Golden Axe, this is an excellent beat-em-up to have on the C64.
