iPhoneFrotz is a port of Frotz, an interpretor for the Infocom and other Z-machine series of adventure games.

Changes:

The Frotz directory has been moved to /var/root/Media/Frotz/Games in version 0.2 so you can use iPhuc, etc. to copy the files more easily.

If you already have game or save files in the old location, iPhoneFrotz 0.2 will move them to the new location automatically on first launch.

This update also enables auto-saving of games when the phone goes to sleep or back to the SpringBoard menu — this worked in 0.1 only if you knew to create the ‘Saves’ directory by hand.
