These are Spectrum snapshots of the Level 9 text adventures.
Those in Z80 format can be played with the emulator "Z80", while
those in SNA format can be played with "JPP". Other emulators
support at least one of these formats.

In addition, all the SNA games (except those in the v1 directory)
can be played with the Level9 interpreter available for MSDOS,
Windows, Amiga and Acorn Archimedes.
