I run Arch Linux on an AMD Ryzen 5. I have mono installed, not sure why, i guess it is a depenency for sdrsharp or the like. However, the sh ./zork1 did the trick :-)
Great! Glad to hear we have a simple solution for this issue. It is interesting to note your trouble, because another player in this post is running Arch and says it worked flawlessly. I guess Mono gets in the way a little.
