How To Play These Exhibits

Exhibits are compressed into zip files. They can be unzipped with a decompressing program such as Winzip or Pkunzip. Once unzipped you can easily determine the game type by the file extensions.

Common Game Data Types:
  1. .z5 or .z8 or or blorb or zblorb - Inform
  2. .gam - TADS
  3. .hex - Hugo
  4. two files, .acd & .dat - Alan
Each game type was written in a different IF computer language which used a different compiler to create the data file. So each game type needs its own type of interpreter to play it (an interpreter is the program that "runs" the data file). Interpreters for the various types of exhibits are available at They are also customized into executables for different platforms (PC compatible, 386, 486; Mac; Acorn; etc.). However, note that not all interpreters are customized for all machines.
