This chip is preinstalled with MM3 USA HEX. It is a modchip with stealth, which bypasses most modchip detection routines found in newer games. It uses an 8-pin PIC12C508a Microchip, which is about the size of an adult fingernail. Plays backups and is region free.

If you are unsure if this will work on your console, please feel free to contact me. 

*NOTE: THIS CHIP WILL ONLY WORK ON AMERICAN CONSOLES, NOT JAPANESE OR PAL Regions.*

Comes with kapton tape on the bottom of the chip to prevent shorts, and 36 inches of 30awg wiring.

Each batch has been verified thru microburn and one chip randomly installed into a ps1 to confirm they are functioning as intended.
