I think you are far better off emulating NES or C64 Elite but the Spectrum, Amstrad and MSX versions are also emulable.

   Spectrum Elite was programmed by Torus and published by Firebird in 1985.

You can find a selection of Spectrum emulators at Planet Sinclair

There is not much difference between the 48 and 128K versions.

   Amstrad CPC Elite was programed by Torus and published by Firebird in 1986.

I have emulated it succesfully (if slowly) using CPE.

• Copy the .DSK file into CPE's DISK directory.
• Run CPE,
• Press F6, and select the   ELITE.DSK file.
• Type RUN"ELITE [sic].

   MSX Elite was programmed by Mr Micro and published by Firebird in 1988.

I recommend emulation with the DOS version of fMSX.

You will need the MSX1, DISK, and FMPAC   rom images in the same directory as fMSX and MSXELITE.DSK.
Run using fmsx -dos -msx1 -diska msxelite.dsk
Save and load commanders as normal.
