One other suggestion would be to review the hardcore computist mags for a possible crack.PROGRAM NAME ISSUE PAGE TYPE Toy Shop 62 29 Bit Copy/Sector Edit Glenn
Quote form the issue: "Toy Shop by BroderbundThe protection is a lot of tracks without normal secotring which are loaded using 4&4 encoding. I good bit copier will copy this this without trouble. Then track $00, sector $0E, byte $09 of the startup disk, I found a JSR to a nibble count at $B800 (20 00 B8). Upon changing that to EA EA EA the disk booted."
So I guess you just bit copy it using Locksmith, Copy II Plus or Essential Data Duplicator II and then sector edit 00/0E/09: from 20 00 B8 to EA EA EA to make the copy work.
Thanxk, Ed
