Also, could you point out the glitches for me? The screenshot posted seems pretty consistent with the flyer..

No.10026 NekoEd Senior Tester Nov 28, 2013, 20:17	As for the graphic glitches, there's a great example in the screenshot he posted at the left-side tip of the ship, where it overlaps the rock, there's discoloration of the tiles there. It happens along every edge of the silver ship where it meets the brown rock, the tile of rock turns red.

The "missing" intro in the non-Japanese sets is much more likely to be a genuine version difference than an emulation bug, especially when you consider that Konami games from this period often had major differences between Japanese and non-Japanese versions (xmen, xexex, thunder cross etc.)
