I don' think this was ever released on its own, but was recently included on Activision's disk-only Power Hits compilation.

I enjoyed playing it, at least for an afternoon. It's hardly the most sophisticated sim around, with a minimal number of available punches and moves, but it has simple sort of hookability.

Rounds are usually closely contested and fights often go the full distance with a panel of judges giving realistic scores.

As well as punching the other bloke's lights out in the side-on arcade section, you get to choose his training between matches.
