Seems like someone over on Planet Virtual Boy's forums has created a homebrew demo version of SF2:HF for the Virtual Boy!
Whilst not my personal preference of hardware, I do enjoy seeing people working on and releasing games for consoles that have long been 'dead'.
Check out some screenshots of the game below:
Unfortunately from what I understand this doesn't appear to work with normal emulators, and has so far only been said to work with original hardware with a Flashboy cartridge.
If for some reason you happen to own both a Virtual Boy AND a Flashboy cart, check out Planet Virtual Boy's forums for the rom.
Also check out the brief footage of the game running via Retrocollect's Youtube Channel:
