Is there a prefered file format for JSW (or generic Spectrum)
patches?

The ones I've done - at
http://www.seasip.demon.co.uk/Jsw/patches.html - use the Intel .HEX
format, because that's what the assembler I was using generates.
JSWED's 48-to-64 upgrader uses the same format.

.HEX solves the problem of a patch covering more than one part of
memory, because it can contain multiple memory ranges. What it can't
do is say "put this bit anywhere there's some free space". For that
you'd need a more complicated format again, such as .REL.
