And I spent the evening experimenting with just that.

http://www.seasip.demon.co.uk/Jsw/experiments.html

The bottom item on that page is a zipfile with two ROM images that
do nothing except load games saved by JSWED. This leaves a lot of
blank space in the ROM - about 14k - which can then be filled with
sprites, or (in JSW128) guardian tables, or (in JGH's JSW48) rooms.
Using a custom ROM image also means that the font in JSW48 games can
be changed.

A couple of problems with this approach:
1. The games are no longer playable on a real Spectrum without
additional hardware (an Interface 2 or compatible device).
2. If I wanted to add this facility to JSWED, I'd have to go to
800x600 first; there's no room to add any more screens when editing
JSW64 games. Just look at the Hex editor while editing a JSW64 game
and you'll see what I mean.
