PSX Mod Chip Installation Including Video Tutorial
The guide here shows the processes of installing an mod-chip in an older grey Playstation as for the newer PSOne the steps are simillar but in general easier.
Removal of the PSX cover
- Be sure that there is no disk inside the PSX and anything is plugged into the ports!
- Turn unit upside down and remove the black screws. (6 pcs)
- Turn unit right side up, and lift off the cover. Make sure that you also save the parallel port connector cover
in a safe place.
Removal of the CD drive
- Pull the flexible orange cable straight up to disconnect it from the motherboard.
- Disconnect the power-connector (the other cable from the CD drive) by pulling it straight up. Be careful,
it´s easy to break!
- Lift off the CD drive and put it to a save place.
Removal of the Heavy Metal Bracket
- Disconnect the power cable from the motherboard. You must disconnect this cable from both end, as it
is fixed to the heavy metal bracket.(at the SCPH 750x)
- Also disconnect the ribbon cable from the motherboard by pulling it straight up.
- Remove the 4 screws holding the metal bracket.
- Lift off the bracket.
Removal of the Metal Shield (SCPH 700x , SCPH 750x)
- To remove the metal shield you have to resolder 8 pads, where the shield is fixed.
Wiring the Chip to the Playstation
- If you have a model SCPH 550x you have to remove the lasting screws to remove the motherboard
from the housing, because all soldering-points are at the bottom (except point "2" or "3").
- Make sure that only a very small amount (about 1mm) of bare wire extends past the insulation on the
wires that you must attach to the Playstation.
(In case that you have a model SCPH 550x turn the Motherboard up side down)
(In case you install a "classic" modchip into the model SCPH 750x or 900x the green wire is just
needed as link-wire with no connection to the chip.
You must cut the green wire!). Don´t make the link wire longer as needed,
- Solder the wires beginning at point "1"(red) and "8"(blue) next "4", "5", "6", "7", and at least "2" or "3"(brown).

Temporary Re-Assembly
You have to reassembly the PSX temporary to ensure that the chip is operating properly.
- Check again all connections
- Resolder the metal shield.
- Put the large metal bracket back to its original place. As you do this , pass the wires attached to the chip
through the small gap between the metal bracket and the metal shield on the bottom of the motherboard.
- Place the chip in the small indentation at the front-right corner of the PSX.
- For now don´t attach any screws.
- Reattach the cables from the powersource and the Controller connector.
- Set the CD drive back to its place at reattach the two cables.
- Put the main cover onto its place.
Testing
- Insert a real, non-pirated game. Turn the unit on and ensure that the PSX boots the game.
This happens if the white Sony-Logo turns into the black Playstation-Logo.
- Insert a real, non-pirated imported game. Turn the unit on and ensure that the PSX boots the game.
- Do this also to your other cds. :-)
- If there are any problems (for example the disk spins at a very high speed maybe the laser has to be adjusted
Final Reassembly
- Simply go to the "reassembly" steps, this time screwing everything in.
- Repeat the "testing" steps.
