ALIEN MIND COPYING
Well I finally figured out how to copy Alien Mind with Copy II Plus.
I've played the first two levels with the copy and it seems to work O.K.
I haven't tried copying disk 2 yet, but I looked at the code and all the
read routines are the same. The Address marks were changed from:
D5 AA 96 to D5 AA AA
Pretty easy huh?
The following are the parameters you need to change:
Parameter New Value Result
----------- ----------- --------
10 AA New Address Mark
12 00 Clear old one???
55 03 Do Header check
02 40 Helps w/ track length
0B 02 Nibble edit at copy time
Now do a complete copy (tracks 0-4F). Keep track of all reads that don't have
D5 AA AA (write down track number). Re-try all the tracks that didn't have the
address marks correct. I only got five, but it varied from track to track
each time I copied. This is a pain, but it is the only way I knew to do it.
Anybody else got any ideas?
Well at least I have a back-up now!!!
I am also working on cracking the program. It's a toughy though. I found all
the read and write routines. I guess these could be rewritten to use smartport
calls and the disk reformatted standardly. I'm not sure. I found a neat way
to use the GS debugger on it though, but I don't want to give away any secrets!
How close is anyone else. Leave me mail on Trebors Castle (#97) or Chemical
Wasteland (#43).
10" Disk ( or PiratePerfect )
P.S. Isn't level five a bitch!
