OK, thanks.
It works to copy all the content of the floppy to a folder and start the game from HDD.
Thanks.
Thanks for the extra build.
But unfortunately it doesn't make a change.
As it seems (I've tried on 3 Amigas, A500 with ACA500+, AOS 3.2; A1200 with ACA 1230, AOS 3.1.4; A1200 with Vampire, AOS 3.2) the game can't be started when copied to HDD. It starts fine when starting from floppy.
Now of course it would be cool if I could just drag&drop the icon to HDD and start it from there. That's what I thought is the install procedure.
I can tell that when I boot without startup-sequence but have the Incaman disk in the drive and start the game by typing "incaman" on the prompt, it works.
However, also booting without startup-sequence but without the disk in drive but loading "incaman" from the hdd it doesn't work. The executable loads but after loading the cli prompt comes back and nothing happens.
