I dont know if its a bug or not but ive tried using a version that isnt b1.1_02 (a1.0.15 & a1.1.1), i get a darker background, unlike a1.2.0 versions or above which have the background lighter
And i recommend for nostalgia to have sound proxies for different versions, for example, a1.0.8 cow sounds instead of a1.0.9s cow sound
