a dongle plugged in the joystick port or serial port, i'm not sure, since it was missing in my ST original. the atari st release uses it too, and an ST cracker has removed the dongle check on the disk 2 if i remember well.

I have checked the suspicious code I found yesterday now and it is indeed a dongle check. Code is like this:

Code:

	move.l	#$BFD200,CIAB_DDRA	; CIAB ddra
	move.l	#$BFD000,CIAB_PRA	; CIAB pra
	move.l	CIAB_DDRA,a0		; set port a directions
	move.b	#%11000000,(a0)		; com line DTR+RTS output
	moveq	#0,d0
	move.l	CIAB_PRA,a0
	move.b	d0,(a0)
	move.b	d0,-1(a5)
.loop
	cmp.b	#100,-1(a5)		; test 100 times
	bcc.b	.done
	move.l	CIAB_PRA,a0
	move.b	(a0),d0
	and.b	#%00100000,d0		; bit 5 = com line carrier detect
	move.b	d0,PROTECTION_RESULT
	addq.b	#1,-1(a5)
	bra.b	.loop


.done	...

It checks if a dongle is connected to the serial port, I don't know why this check passes, either it's because the system uses the CIAs (game doesn't disable interrupts ect. before performing the check) or the result check is wrong (is bit5 (com line carrier detect) in CIA B/port A low active?).

I have checked a bit more now, it seems the protection checks are never called, played the French version for quite a while and the protection checks never occured. No idea when or if the protection is checked but I disabled the dongle checks anyway.

If this game was not that rare, i would have done something better

Sorry for proposing ADFs with missing files....

No worries, such things can happen. I wonder why there are so many files missing in your version though.

i guess that the original disks i made the ADF from (not mines unfortunately were already modified and badly with that).

Maybe the protection has been tampered in files of the ackerlight release ? I don't know and can't check that.....

However, i think i have scans of the box and the manual.

EDIT : i do have them

Meaning i will be able to create boxscans of the french release + a little manual
