Summary	07829: superchs: Train with enemies appearing too soon during attract-mode
Description	Bug originally reported by pri88 in 00025: During one level in attract-mode, a train with enemies appears out of place. It should appear right after leaving the tunnel. They appear as soon as the level starts in attract mode. Here's the bug in MAME: Next video shows attract mode in the original hardware. The bug is not present here. The train appears later, after the tunnel. This part of the attract mode can be seen in 29:24 As seen comparing both videos, the bad guys should appear after the tunnel, not before. No regression version found.

No.18306 Haze Senior Tester Dec 31, 2020, 20:09	ok, it isn't the speedup
