DISCLAIMER NOTICE – Please read this before installing your chip

This modchip is not designed as an official product to be used with the Sony Playstation. Playstation is a registered trademark of Sony Computer Entertainment. The modchip is a microcontroller that has been programmed with specially written code/software that allows it to function as a modchip. The software in the chip is also not licensed by Sony Computer Entertainment.

This modchip is sold to you on the understanding that

I and my re-sellers will not be held responsible for any damage to your Sony Playstation caused by fitting this chip.
I and my re-sellers will not be held responsible for any misuse of this chip.
You understand that by fitting this chip, it will invalidate any warranty you have on your Playstation.

If you continue on with this installation then you have agreed to all the terms above.


 You will need a soldering iron with a very fine tip, not one that’s the size of a spade as there are some fine soldering points. If you are not too good with a soldering iron then I suggest you do not fit this chip yourself.

1. Removal of the Playstation cover.

Disconnect the power to your Playstation. Use a hairdryer and sharp knife to remove the guarantee sticker. Remove the screws from underneath. Turn right side up and lift the top cover off.

2. Removal of the laser.

[Do this very carefully, if you damage the cables you will need a new laser unit – these do not come cheap!]

Pull the ribbon cable straight up gently by the white card bit. Gently disconnect the grey wires by pulling straight up. Lift off the laser unit once all wires are free.

3. Removal of the silver shielding.

Carefully lift the shielding straight up.

4. Prepare chip & board.

Tin the ends of the wires and the points on the board to be soldered.

5. Fit chip to board.

Solder the wires on your board using the points shown in the diagrams. The chip will have to rest on top of the main circuit board (below the metal shield).

6. Finish off.

Once you have soldered all the points double check to make sure you have not soldered between any 2 points that were close together, and to see all the wires match the pin numbers. If you have installed this kit correctly then your Playstation is converted. Reassemble your unit and CAREFULLY screw the case together. Only re-attach the sticker once you have tested the unit.

Additional Hints

Using this chip, it is not possible to play imports directly. However, there is a special boot CD available which will allow the use of imported games on your chipped PSOne. This CD will also take care of most video conversions, however you may need to use an RGB SCART LEAD between your Playstation and TV.


It seems that when a machine with a chip in it exhibits some sort of problem or perceived deficiency, the mod chip is the first thing everyone blames. Folks, in 99% of the cases THE CHIP IS NOT THE PROBLEM! Here is a breakdown of common problems and their likely causes.

This is almost always an indicator that a wiring mistake was made. It is very important to have clean, well-formed solder connections to the board wiring points and the chip. If any of them are wrong or are poorly soldered, then the chip is not going to function properly. The chip is not the problem – the installation is. Double-check and re-solder suspect connections. Make sure wires don’t get trapped under screws. Make sure the wires don’t short against other circuit points.


Machine comes up with CD menu or "Insert CD-ROM" screen

This is almost certainly a wiring error. The only way this can happen is if the mod chip signals are garbled by poor wiring or missing or improper wiring. The difference between CD-R and masked production discs in regard to booting is large enough to allow for this uncommon problem.


My backups boot, but my originals do not (very rare)

As mentioned earlier, the PSOne will not play imported games - even once chipped. You MUST use the EuroBootCD.


This is a common question, you may need an RGB SCART LEAD for it to play in colour.

My imported games/backups do not boot
Imported games appear in black and white on TV
