[hatari-devel] Ishar 1 and 2 falcon

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi,

I've given a closer look at ishar 1 and ishar 2 on Falcon.
They are both "installed" on my hatari falcon hard  drive in a directory 
Ishar_1 and Ishar_2.

When I launch them, the program loop forever in these lines :

cpu video_cyc=  1424 400@  1 : 000510C2 48e7 8000 MOVEM.L D0,-(A7)
cpu video_cyc=  1436 412@  1 : 000510C6 3f00 MOVE.W D0,-(A7)

The Trap BIOS 7 is : get floppy disk boot sector. This means that a 
floppy disk has to be present in the floppy disk drive.

So, the problem with Ishar 1 and Ishar 2 is absolutely not a problem of 
Videl or cycles or whatever but just that the games should be on floppy 
disks and not on the hard drive.
(From what I understand of the problem).
Can someone confirm ?
