ROM hackers have released Tecmo Super Bowl roster patches for years now, but Tecmo Super Coach does more than just update the 1991 NES game's team lineups for the 2009-10 season.

Tecmo Super Coach, which first appeared late last year for the 2008-09 season, takes the original Tecmo Super Bowl and overhauls quarterback priority selection, makes CPU play-calling less predictable, adds "strategic situational play calling", and throws in lots of other hacks intended to help create a more "realistic Tecmo Coaching experience".

The patch won't be available until later this month, but you can already flip through Tecmo Super Coach's online instruction book to see the complete list of changes and hacks.
