Works now, thanks. I really like the japanese level-order more. Had you recognized the other two mentioned things (floppy-motor and the problem in Lv2 on the second floor there, when running on the conveyor-belt)? The other three levels run well on A500, only in this second level there are some problems, but only on the second plane there, it seems. On a A1200, there's no problem in Lv2 (tested it today), so it has definately something to do, with missing speed on Amiga500 machines. Seems like Level2 needs more CPU-power, than the other three levels of the game. Can something be done here, then it would also run well overall, on A500 machines, or has everything already been maxed out?
Only on the second floor in level 2, i have speed problems on my Amiga-500 machines (and when this level repeats itself, later in the gameplay, of course), when my sprite is on a conveyor-belt. The rest of the game really works very well, on 7MHz OCS/ECS Amigas. About this floppy-motor thing. I will look on the disk, if this file is there. If this is the case, you mean, that this problem is gone? I also asked this motor-thing, because in the last years, I've encountered more than one time, a problem with various new demos or games for the Amiga that were released on the Pouet.net, where the programers forgot, to reset the _MTR-Signal in the CIA or something similar to this and then the software sometimes goes on loading on real floppy-drives or the drive-LED always stays on, even when the Amiga game or demo, is already fully loaded and running. Maybe this also is a consequence of programming in emulators, not sure?
