Unfortunately, it seems that quickstarts exclude ballparks.
Here's what I've got - logos for ***, ni-gun, BCL, and SILP teams are accurate, as are most of the uniforms (I don't have any for the Tochigi Golden Braves or Shiga United, and Orix's away is too bright). Rosters are same as current patch, and I only slightly tuned the ruleset:
* Teams will play tiebreakers
* No HR derby
* Climax Series Final Stage is best of 7 - save-scum to get the top seed the one-game advantage they deserve
* Ni-gun roster limit is 50 - *** orgs are limited to 70 players + whatever
ikusei developmental guys they sign.
For the ballparks, try
here for the *** teams, and
here for the ni-gun.
