Safe exploring: Copy disk two and create your party on both disks.
Begin game play and insert the disk two copy before any secret
doors are discovered or doors are unlocked. This forces the game
to write the current status to the backup disk. Replace the original
disk and continue game play. If the party becomes stuck and the
game must be restarted, continue with the backup disk to have
all doors previously locked opened and have a surplus of keys
after they are collected.
