Prince of Persia

The 1996 ZX Spectrum port was a pirate conversion made by Russian cracking group.

If we still want to list it (I'd suggest only as trivia entry), at least put a note somewhere about unlicensed version.

We enter cracking groups as companies...?

Any devteam with a name and releases, officially licensed or not, and whatever their side activities, is still a devteam worth documenting. Without them we wouldn't have eg. Ms. Pac-Man.

Sent back, shouldn't be listed alongside. If it can be played without modifications, it can get a separate entry.
