It's more that everything feels crazy stiff and I can't really get most of the special moves out. Even stuff like P+K doesn't seem to execute correctlyDynamite Cop was made for arcade and SoR was made for home consoles, and I think there's a corresponding difference in the difficulty curve and the philosphy behind the difficulty balancing (eat your quarters vs. provide a challenge).
So, don't feel bad.
I theorize that there are a lot of classic games like this that people claim to really like and even recommend (all based on a kind of theoretical admiration) but don't actually take off the shelf and play.
