Purchased pre-modified from an eBay seller, this PS1 was then further modified by TopVint. You can find his write up of the work performed here.

Multi Frequency Oscilator

In Game Reset

SIO-X Switchboard

Output is handled by a RAD2x cable and the controller of choice is a 20th Anniversary Dual Shock 4 controller connected via an 8Bitdo Bluetooth receiver. I also use a MemCard Pro and have a PocketStation for no real reason!

Software is largely handled by a PSIO.
