There are a few bugs and it isn't completely implemented, relies on script numbers and other shenanigans.
Should break it out of the pk3 and use a simple config of sorts to build it with from a selection of examples that each reside in their own folder.
There was a file naming issue (ZMemoryx.y.z.pk3 instead of ZMemory_vx.y.z.pk3)
This has been fixed.
The file on the release has been updated as well but the commit pointed to the tag hasn't been altered. It isn't important at this stage anyway.
