I tried out Daphne with Dragon's Lair (original) today, and just about everything seems spot on... except for the falling disc-platforms. The timing seems excruciatingly precise on these -- so far, I've cleared the jump exactly once, and the second time the scene came up finished my game.
I'm quite familiar with the arcade version and its timing, and it's not as if it's a particularly complicated section (just hit Left at the proper time)... Is there something I'm somehow missing here?
My system is an Athlon 1300 with a 32MB GeForce2 (Win98 SE), and the game seems to be running quite smoothly at all times, so it shouldn't be a lag issue. I'm running from an MPEG (Best Buy has the DVD, which I'll pick up next time I'm there), difficulty level is Easy. Well, easy everywhere BUT on this scene.
