Select (which represents the native PlayStation CPU speed).
High-Level Emulation (HLE) attempts to simulate the BIOS without an official file, which often causes "core stopped" errors. Go to Config > BIOS and ensure you have a legitimate BIOS file (like SCPH1001.bin ) selected rather than using the HLE option.
This error typically triggers when the emulator's core processing loop encounters an unhandled exception while executing a game's code. This is a common issue with heavily modified ROMs, custom game hacks, or misconfigured emulator settings.
Go to , click Bios , and look at the path selection window. Make sure it points directly to an official PlayStation BIOS file, such as SCPH1001.bin , inside your active ePSXe folder. If the path is correct but the emulator still crashes, your BIOS file might be corrupted and need to be re-dumped from your physical hardware.
