In doing some overhauls, I found the Baseball Simulator 1.000 rom has empty space (in terms of team logo and player data bytes) to accommodate all 30 MLB teams (and 2 All-Star Squads as well). This isn't to say I'll be able to manage the various byte swaps, etc. by opening day, just that it's POSSIBLE. So I've added the player data and team logo sprites into the rom, hoping I'll eventually figure out the rest. Here is the most current version of all 32 team logos:
Also, the previously discussed "Lift" value for batters is a modifier which subtracts from a players total power when the ball isn't hit squarely (A similar stat is used in the RBI Baseball rom).
The hurdles at this point are finding the team select screen hex and modifying it (and team tile data hex) to add the new teams. Then I'll need to find a way to give the new teams their own color schemes.
