Inf2ATR
This is a little program I hacked together in plain C to convert story files in Infocom's Z-Machine format to an ATR image, complete with interpreter and all, so they can be easily played under the Atari800 emulator.
It works with all Infocom story files in version 3 that I know of. It does, of course, not work with other versions.
The program can be built and run on most modern Unix-like systems. It will probably not build on Microsoft Windows platforms with a few modifications.
