Sony PlayStation Region Free Mod Kit


Mod Kit Includes:

  • 1 x PlayStation Mod-board (Mayumi / Stealth 2.8a / ONEChip / MM3)
  • Pre-attached adhesive pad


  • Makes the PlayStation region free
  • Allows running 50Hz and 60Hz software for full screen, full speed gaming
SKU: KIT-PS1-RF Categories: , ,


The PlayStation Region Free mod allows you to enjoy import games on your region locked PlayStation console.

When the mod is correctly installed, the console will be region free and able to bypass any region protection of imported games (unless it’s a Japanese PlayStation which have an extra BIOS check).

This also works as a 50/60Hz mod because playing NTSC games will force the PlayStation to run in 60Hz and playing PAL games will force the PlayStation to run in 50Hz.

The modchip can be written with any code to be compatible with any revision of PlayStation 1 console.

The following is recommended based on console revision.

  • Stealth 2.8a for SCPH-100X
  • Mayumi v4 for SCPH-550X, SCPH-555X, SCPH-700X, SCPH-750X, SCPH-900X
  • ONEChip for SCPH-102
  • MM3 for SCPH-10X

Important Note

If you have a Japanese PlayStation, region protection can not be bypassed with a chip.

This mod kit is sold as a region free mod. I do not guarantee that your PlayStation will be able to read discs without skipping. There are many factors that determine how well your PlayStation can do this. CD Media, CD Burner, Burn Speed, Disc Image Quality, PlayStation Lens Condition and Calibration. If a game hits the black boot screen that shows either SCEE, SCEA, and SCEI, it means the chip has done its job and is working.
