Seemingly to inflict more suffering upon himself, Matthew Garrett (lord of getting things to boot using EFI) decided that booting directly into Zork would be cool. Quoting his weblog entry: "So, Frotz seemed like the natural choice when this happened. But despite having a set of functionality that makes it look much more like an OS than a boot environment, UEFI doesn't actually expose a standard C library. The EFI Application Development Kit solves this particular design decision. Porting Frotz ended up involving far more fixing up of Frotz bugs that tripped up -Werror than anything else. One note, though - make sure you include DevShell in the list of required packages at build time, otherwise file i/o will mysteriously fail." Grab the code, assuming you have a copy of Zork (or any other Z-machine game, as long as you name it ZORK1.DAT, I think).
