An independent coder has released Frotz Z-Machine Interpreter 0.1, a free application for Apple's iPhone that runs games based on the Z-Machine platform -- used primarily in text adventures by Infocom like the classic title Zork. Players usually control games by typing in simple verb-noun combinations such as "open chest" or "go north" as they navigate such titles as "Adventure" and "Rogue." Installing Frotz requires a "jailbroken"/sshd-enabled iPhone, as well as the ability to copy a new folder onto the device. "Jailbreaking" an iPhone effectively removes the read-only mode set by Apple to prevent iPhone owners from modifying their phones.
