Source

nullDC is a Dreamcast emulator for PSP, written in C++.

The emulator was originally developed in 2008 by drk//Raziel (aka skmp). The source code was lost for many years; it was finally compiled and restored by xiro and hlide in 2021. It is currently in an experimental stage.

Features

  • GDI format support.
  • DC CPU Downclock.
  • Underclock AICA.
  • AICA Hack.
  • New XMB UI.
  • Running with Interpreter.

Installation

These DC Bios files are needed in the data folder:

  • dc_boot.bin
  • dc_flash.bin

Only games in the .gdi format are supported for now. Place the files for each individual game within a separate folder, and move the folder to /nullDC-PSP/discs/.

The list of available games will then appear when you boot the emulator.

User guide

See the game compatibility list or add a new entry to the list.

Note: The on-screen frame rate is calculated through Vblank - which does not always correspond to the actual frame rate.
