Beetle/Mednafen PCE FAST requires the following BIOS image file for CD emulation to work:

  • syscard3.pce (PCE-CD BIOS)

Any CD-ROM System BIOS will work, but some them are known to be incompatible with certain games.


This core has a few options that can be tweaked from the core options menu. The default setting is highlighted and in italics:

  • pce_fast_cdimagecache (disabled/enabled)(restart): Caches the entire CD image. Can potentially decrease loading times at the cost of increased startup time.
  • pce_fast_nospritelimit (disabled/enabled): Disables the sprite limit.
  • pce_fast_keepaspect (enabled/disabled): Keep the aspect ratio.
  • pce_fast_initial_scanline (0/1 through 40): Position of the initial scanline.
  • pce_fast_last_scanline (242/241 through 210): Position of the last scanline.
  • pce_fast_cddavolume (100/90/80/70/60/50/40/30/20/10/0): Volume of the CDDA.
  • pce_fast_adpcmvolume (100/90/80/70/60/50/40/30/20/10/0): Volume of the ADPCM.
  • pce_fast_cdpsgvolume (100/90/80/70/60/50/40/30/20/10/0): Volume of the CD PSG.
  • pce_fast_cdspeed (1/2/4/8): Set the speed of the emulated CD drive.


The Beetle/Mednafen PCE FAST core supports two different controller settings:

  • PC-Engine Joypad: PC-Engine Controller
  • Mouse: PCE Mouse
