Faery Tale Adventure

Take a save game file and use a PD program such as
NewZap to patch byte 18 to a non-zero value. Load
your save game, and now these cheat options are enabled:
Arrow Keys - Move Rapidly over any terrain
B   - Summon Gold Swan
R   - Rescue Princess
=  - Display coordinates
F10 - Location in coordinates
F9 - Increase time by 1 hour
Sometimes you can accumulate all the treasure you want
by going near the item, pressing space bar, and then
continue hitting ‘T’. You’ll receive an infinite supply
of that treasure.
