This is the classic sign of a missing or incorrect PlayStation BIOS. Ensure you are using the correct region (e.g., SCPH1001 for US, SCPH1000 for Japan).

Most older consoles (NES, SNES, Genesis) do not require a BIOS because Lemuroid uses High-Level Emulation (HLE). However, the following core-specific platforms strictly require distinct BIOS files: Required File Name(s) Function / Notes scph5501.bin (or scph1001.bin ) Resolves black screens and optimizes compatibility. Nintendo DS bios7.bin , bios9.bin , firmware.bin Required for the MelonDS core to load and save properly. Sega CD bios_CD_U.bin , bios_CD_E.bin , bios_CD_J.bin Required based on the region of your games. Sega Saturn saturn_bios.bin Direct firmware required for booting games. Neo Geo neogeo.zip Necessary for the arcade core to read region data.
