are you running from floppy disk, HD or whdload package?
Floppy disk versione works, whdload on Amiga 1200 doesn't start. When i doubleclick pooyan icon It asks for arguments.
there's no icon with whdload on that game (that's missing). You'll have to just enter no arguments (standard run without whdload) or use a CLI and type "whdload pooyan.slave"
