What It Does...



We have developed a replacement BIOS solution for the following consoles that allows them to be completely Region Free.
All BIOS's come pre-flashed onto flash memory which is soldered onto a drop-in replacement pcb.

Each BIOS PCB can hold up to 4 BIOS's, so you can choose which one you would like with easy solder jumpers.

Below is a table of configurations you can choose for your console.
Beginner - Moderate level soldering required, this requires removal of the original BIOS chip and soldering in the replacement one.
We take NO responsibility for failed installs which renders the console in-operable, we do however offer an installation service.
DISCLAIMER: You are not paying for the BIOS itself, you are paying for the PCB and Flash Chip.

Installation...


Step 1. Use precision side cutters to snip the legs off the chip, or use a hot air station to remove chip just in case you want to revert back to stock.

Step 2. Use Desoldering Wick to clean the solder pads of any left-over solder and make sure the solder pads are flat to touch.

Step 3. Place the replacement BIOS PCB over the pads and solder each side to the corresponding pads.
