First and most noticeable, the combo's are completely missing. You'll simply repeat the same slow punch/kicks with no uppercuts or roundhouse blasts to break up the monotony. Since your punches are obscenely slow, the enemies make every attempt to get their licks in every time you swing...at least on the harder difficulties. Mercifully, the soundtrack has been retained, only broke up by the sound effects which occasionally cause a stoppage due to the sound chip's limitations. It's represented here as best it can, but strangely, the end of the level short track is noticeably absent. The ending theme is also gone, along with any traces of a decent ending. Credits? Nope...none. One of the key points (and downfalls) of this one are the humungous sprites which take up a majority of the screen.

The detail is jaw-dropping at times, nearly a carbon copy of the arcade game. This causes issues with the backgrounds however. Since so much scrolling is required, you'll constantly see just a plain gray ground which is not sufficient for a background in any game. The final level really brings this issue up front since your unable to see upcoming pits o' doom resulting in more than a few unwanted deaths. Die-hard fans of the game will find an interesting port of a classic game, but by no means the be all, end all of ports. The minute changes of the gameplay are enough to screw this one up enough to make it a mundane attempt at recreating the arcade experience in portable form. Purists need not apply.
