Perhaps you're correct. I do remember Donk Donk not responding correctly, though I don't recall having problems beyond that. [That is, I don't recall... I also have a terrible memory]. I agree with you on the game's mixed messages. Relax and have fun... while I totally screw with you!
I think the main reason I mentioned different setups was that I had an odd occurrence with the game Fire Pro Wrestling Returns. The FPW games are highly timing-based when grappling and executing maneuvers. I played that particular game on two different HDTVs, and both had slightly different timing. Since that experience, I've always second guessed my own reviews of timing-based games. I'm always afraid I'm going to say, "Yeah, the timing's great!" when it really isn't great for most people.
