  1. One of the secrets of fitting a modern, standards-compliant Z-machine interpreter in 64K is that we don't keep all of it in memory all at once. By this I mean two separate things: 1) once we determine what Z-version the game is, we can throw away a bunch of code that only pertains to other Z-versions. Z3 games can have 255 objects so object IDs are 1 byte, but Z4+ games can have 65535 objects (2 bytes). Two libraries, but each game only needs one.
