This was a collaborative effort between myself (hex editing), Bodom and stalltalk (ratings). There are 24 teams on the ROM. I kept most of the original teams, with a few exceptions (Hartford out/Anaheim in, San Jose out/Dallas in, New Jersey out/Nashville in, Quebec out/Colorado in).
I based the rosters off of the depth charts on RotoWorld.com.
Also, to give the game more of a Tecmo feel, I swapped out the main game font and replaced it with the font from Tecmo Super Bowl.
