Ok I am a total newbie when it comes to emulators. I am more of a woodworker who decided to build an arcade machine who got lost in the electronics world. I have most of my systems up and running except the PlayStation. I have done everything that I can find to do, but still no luck. I am running a Raspberry Pi 3 with RetroPie version 4.0.2. I have added scph1001.bin to the bios folder, downloaded the multiple game pieces and added them to the rom folder. What am I missing? Any help would be appreciated. Please remember I am a rookie so keep the responses and simple as possible lol.
