Space Ace is affected by an issue in which the game goes to the wrong sequence when you play it. So clearly the emulator is picking the wrong mpegs to play in the wrong order. If it happens with that game, it seems likely it would be happening in this game.
The video you posted on YouTube never even gets off the bridge. Plus I am not sure if it is real hardware or the emulator. So I'm having to assume we were talking about the same issue here. It doesn't make sense that the real magic release was bugged. It's a very simple engine and it has been released on dozens of platforms. For them to get this release wrong is not the most logical conclusion to the game not performing correctly.
I'll order a card and test them myself. You can't assume the emulator is perfect just because you can get through a few scenes.
The original MS-DOS version would get halfway through the game before it started skipping scenes. But once I bought a clean copy of the game and set everything up from scratch, it ran perfect.
Would you mind telling me which realmagic card works best? I know you have tried many, and found issues with several of them. Thank you
