Fast computers do not alleviate the problem of

Actually, JSW128 and Geoff
Mode could badly do with a save-game feature, as they
are extremely prone to crashing on a real Spectrum!
:-( (Matthew-Mode JSW48 games rarely
crash).
It's particularly a big problem for me with JSW128, as
my emulator doesn't support 128K mode well enough to
play JSW128 games, and there's probably no way I could
get through a 4hr+ marathon on my real Spectrum, all
in one sitting, without it crashing.
So I
could do with JSW having a save-game feature, which
would have to serialise your current position (room
number, Willy's co-ordinates, whether in the middle of a
jump, current time-frame and positions of guardians).
It probably would entail saving the room-buffer
(starting at 32768: 256 bytes for the room, followed by a
72-byte guardian buffer), plus some variables, plus the
item table.
