Hi Presh, congratulations on your amazing "homage"; this is how the Spectrum conversion of Street Fighter II should have looked and played back in 1992.
I can confirm that the game works on a real 128 Spectrum with a DivMMC EnJoy interface and on the latest version of SpecEmu, with and without DivIDE emulation.
If I may suggest you something in order to further improve an already impressing result, it would be:
- a disk-based file, preferably TR-DOS, because it is readable by many emulators and compatible with ESXDOS for use with SD card-based interfaces;
- fighters portraits before the match, like in an enhanced hack of Street Fighter II you can easily find on the Web;
- end-of-game messages for each character;
- the possibility of changing the stage colours;
- scoring.
Thanks again for your time and effort and for making it available to us all.
