Dynamic Objects hasn’t been updated since 9.1/6L02 in 2014. It has known problems in 9.3/6M62. Unless some solitary hacker is keeping it to themselves, no one has an up-to-date version.
I still find it very impressive it was ever written, given that there wasn’t documentation on a lot of the underpinnings it makes use of. The good news, such as it is, is that Inform being open source puts one in much better stead to attempt such a thing today.
Details not relating directly to language changes often miss getting updated. It’s been a lot longer since Mistype by Cedric Knight was current.
I like the cut of your jib.
