I see a couple of possibilities here. You could produce 'embedded .Z80'
and .SZX images. You could produce a ROM that can load the rest of the
game from tape (like SotU). This could be loaded as an IF2 cartridge on
some emulators. You could also produce a fully software version for
machines that are able to use RAM in the 0x0000-0x3FFF area (Spectrum
+2A/+3/SE).
My personal preference would be for the IF2 cartridge approach. You
should be able to save a .SZX snapshot after the game has loaded (from
..TAP or .TZX), it is easy to convert to software only for the SE (and
the +3/+2A as long as the total code length is 128K, only the SE if you
go over that). And it gives people the chance to use it on a real
machine by burning an EPROM for use with a real IF2.
BTW, were you planning on doing a 64K game or a 144K game?
