So I had been wanting to know this for like 3 years but all I could find on the forum regarding changing all-star uniforms was to manually change all the team uniforms to the all-star uniform. Yeah no thanks...
Then I stumbled onto this thread
https://forums.ootpdevelopments.com/...d.php?t=262034 where I learned how to change the all-star logos.
Then I was searching around in the files of OOTP on my computer and found out you can actually manually import jerseys - infact OOTP has instructions on how to do this in a readme document in the jerseys folder. I'm guessing a lot of posters know this already but for the schlubs like me who don't read the readmes here is how you change the all-star uniforms so you don't have to change every teams uniform.
In the OOTP folder locate your league folder ".lg" under saved games.
Locate the jerseys file. Locate allstar team name - replace both files with jersey files that you have made. The file name should be jerseys_ + team name + underline + team nickname + .png. Example "jerseys_south_league_all-stars.png". Reload league and the all-star jerseys should be good to go.
Now if anyone knows how to change the color scheme that'd be great to know. The catcher's gear and team/player colors are off.
Thanks
