I wrote a very simple, incomplete game using Inform7, which has the option to compile to Z-Machine code (zblorb files), version 8 as I recall.
I copied the zblorb file to the BE and ran it with XYZZY, but I got a version error and it wouldn't run. I looked into the AZIP project a bit, but before I dive down that rabbit hole, I wondered if anybody else had tried using Inform7 files using the zmachine that comes with the BE. I would love to be able to write some interactive fiction for the BE.
