As far as I know, the reason why you can set MusicSelectTime or any other item in mai2.ini, is because that version of game was modded by someone. you want to change the items of real 1.35, such as music select timer, you need to decompile the Assembly-CSharp.dll , find "MusicSelectProcess.cs" and change number of like "PrepareTimer(65535, 0, isEntry: false, TimerCountUp);" . Any other items you can just search the key word like "Select" "Process" etc..
