Action Replay USB Link

Introduction

This is a replacement for the Datel "Comms Link" ISA card which is used to control an PSX or Saturn Action Replay cartridge. It connects the cartridge to a PC through a USB interface that roughly matches the speed of the original Comms Link card.

Features include:

  • Can upload and download data from anywhere in the Saturn's address space.
  • Programs can be uploaded with communication back to the PC for virtual CD filesystem emuation.
  • Functions for dumping the BIOS and Action Replay ROMs.
  • BRAM saving, loading, and formatting.
  • Detection of Sega Saturn chip revisions and cartridge features.
  • Diagnostics to determine transfer rates.

Project status

Currently there is no support for the PSX Action Replay. The focus is on the Sega Saturn and primarily in program development and hardware testing. This makes the Action Replay USB Link ideal for people who want to write software for the Saturn without having to rely on writing CD-Rs.
