@blackshadow13 Apart from samples for some games, there's also those that have CHD files for them. I saw a set and it was huge and well over 120 GB. If you do have to get a set i recommend a macchanger and VPN for pc anonymity. You know because Nintendo has been harming emulation and is trying to label it as piracy.
