Required for North America/US-region games. Do not rename other revisions/regions of the BIOS to match the expected filenames, or you'll likelyĬause emulation glitches(and cause confusion if you ever distribute or otherwise refer to these misnamed files). Place the correct BIOS image files in the correct location. Set volume too high, leading to obnoxious clipping in the emulated SPU.Erroneously use load instruction target register as a source register in load delay slots.Perform unaligned halfword and word memory accesses.However, many PSF1 rips won't work properly as they are broken in various ways: For better performance, the binary should be compiled for a 64-bit target(for example, x86_64) rather than 32-bit, if available.Įnabling CD image preloading into memory via the cd.image_memcache setting is recommended, toĪvoid short emulator pauses and audio pops due to waiting for disk accesses to complete when the emulated CD is accessed. Running Mednafen's PlayStation 1 emulation on(note that this recommendation does not apply to any unofficial ports or forks, which may have higherĬPU requirements). For any given game, either use save states or the game's own save system, but not both, lest you may destroy your saved games.Ī dual-core Phenom II or Athlon II at 3GHz or higher, or rough equivalent(in terms of single-core IPC), is recommended for WARNING: Save states(and by extension, state rewinding and netplay) and saved games on emulated memory cards do not mix well unless you areĮxtremely careful.
