Once the BIOS is in place, you can continue to configure ePSXe. The emulator cannot read the ZIP file, only its contents. Once you have pasted the BIOS archive into the correct folder, you need to extract the contents. For example, my ePSXe BIOS folder is C: Users Gavin Downloads ePSXe205 bios. The location of your ePSXe BIOS folder depends on where you extracted the emulator. You will find the BIOS directory in the ePSXe folder. Once you have extracted your PS1 BIOS, you need to copy and paste the archive into the BIOS directory.
