The BIOS must be called scph1001.bin and be placed in the __SCE__ps1p directory along with the BIN, ISO, IMG, Z or ZNX images. Other BIOSes should work too but rename them to scph1001.bin because the emulator looks for this file specifically.
People can use PocketISO (google for it or the FPSEce page) to compress images to Z and ZNX.
The ePSXe memory cards must be renamed to mcd001.mcr and mcd002.mcr and placed in the __SCE__ps1p directory.
