Important Message

COVID-19: Mod kits to UK addresses can be posted with a second class large letter stamp via a post box so there is no restrictions or delays for me to post these. Install services and international orders need to be taken to the post office and might be affected by movement restrictions in the UK and potentially have three weeks of delay from 23rd March 2020. I am really not sure. Thanks

Sony PlayStation In-Game-Reset Install Guide

This install guide is for PyroESP's reset mod for the original PlayStation. The mod allows In-Game-Reset functionality which is a great benefit for PSIO users.

SCPH-100X PU-8, SCPH-550X PU-18, SCPH-700X PU-20 and SCPH-750X PU-22 are covered. SCPH-900X PU-23 and SCPH-10X PM-41 are coming soon.

Controller Port Connections

The controller port is the same for all PlayStation revisions.

SCPH-100X PU-8

Straight forward bottom mount install. Wire run for RST is longer than desired and will cross over wiring for a PSIO install. Chip placement has no risk of obstruction, shorting or wire crushing.

SCPH-550X PU-18

Straight forward bottom mount install with short wire runs. Chip placement has no risk of obstruction, shorting or wire crushing.

SCPH-700X PU-20

This revision has a large RF shield covering the top of the mainboard. It does not need to be removed to install the mod, but it does limit where the chip can be placed. The below diagram presents two options for chip placement. Possibly the only two feasible locations for the chip.

SCPH-750X PU-22

This revision has a large RF shield covering the top of the mainboard which severly limits where the chip can be placed. Stick the chip to the bottom of the board and rout the wires through the hole. This placement has been chosen because there is no risk of shorting or crushing wires and the wire runs are short and direct. Placing the chip any further towards the right may result in obstruction and possibly shorting. Keep the wires for RST, 3.5V and GND straight and routed on the inner side of the pins.
