The PES 2021 new net sounds by guorfan mod will allow you to choose between 19 different net sounds for your pes 2021. I took idea from flokiman and SoulBallZ really nice work with first version, I think this had much potential to increase number of different options to choose.
Actually I would like to have different net sounds for different nets into different stadiums but it seems thats not possible for now cause audio files can not loaded as addon into different stadiums so if you choose an audio file, this audio file will be reproduced in every nets from every stadiums in livecpk.
How to install?
Take an audio you like for your nets and inside number folder there is a folder called livecpk, copy this folder into your sider directory and add this line into your sider.ini
cpk.root = ".\livecpk\NetSound"
