This is a generic uni mod for All-Star Games/Home Run Derbies for the '50s and '60s. Included are the uniforms, fonts, and uniform select screens. Please note that this mod will add one new uni slot per team. Due to coding limitations, old timey equipment is unavailable, and you might notice the MLB logo from the helmet on the back of a batter's head. Another issue I came across was the socks and the fact that the uni select screen says the jerseys need to be unlocked. This isn't true. You can play just like normal.
To install, simply use TiT. Always remember to back up your files. Enjoy!
