Actually, the main space waster in the proposed savefile format is the
object list. Each 40x22 dungeon can be stripped down to 660 bytes of
data, but unless I go for a more complex save format I'll also be
saving 202 objects, which are 8 bytes each. If on average each dungeon
level only contains 30 items, that'll be over half the save file
wasted with empty definitions.

If I have the time (or a really good idea) I'll go for a more complex
save format, but the limits of DFS, BASIC, and 32K of RAM will be
working against me. So for now I'm just sticking to storing a fixed
size block of data per level.
