Daedalus is a Nintendo64 emulator for Windows and PSP. Daedalus is named after the craftsman at King Minos's court who designed the labyrinth for the Minotaur.

This release of Daedalus for the PSP is currently in early stages of development. It is intended to show the potential for a N64 emulator on the PSP, but the current release has many missing features that make it far from usable:

• There is limited savegame support.
• Not all the N64 controls can be used simultaneously.
• Many roms won't boot.
• Many roms have serious graphical glitches.
• Many roms have random lockups and crashes.
• Many roms run at a low framerate.

See also the compatibility list on PSP Developer Wiki.

Installation

Copy the Daedalus folder to the /PSP/GAME/ folder on your PSP.

User guide

Roms

Roms should be copied to the Roms subdirectory within the Daedalus folder. Daedalus recognises most roms formats (.v64, .z64, .rom etc) and will also run roms compressed within .zip files.

NB: Recent versions of Daedalus will also load any roms found within the /N64/ directory on your PSP. Note that this is in the root directory of your PSP.

When Daedalus boots with a zipped rom, for performance reasons it will attempt to decompress it to a temporary file on your Memory Stick before execution. If you are low on free space, it is recommended that you keep the original rom file on your PC, and manually extract the rom to your Roms directory.

Preview pictures

Preview pictures for the rom selection screen can be added to the Resources/Preview directory in the Daedalus folder. They should be in .png format, in a 4:3 aspect ratio.

To let Daedalus know which picture to use for each rom, you need to add a line to the corresponding entry in the main daedalus.ini file, with this format:

Preview=<filename.png>

Where <filename.png> is the name of the .png file. Don't include any directory names in the path.

Save games

Currently Daedalus PSP has limited support for the following save game types:

• 4Kb Eeprom
• 16Kb Eeprom
• Mempack

Save games are created with the same name as the rom file, in the Daedalus/SaveGames/ directory.

Important note: For performance reasons Daedalus only saves out modified save game files when the Pause menu is accessed (by pressing the 'Select' button while the emulator is running).

Main menu

When you run Daedalus, it will present you with a list of all the roms it could find in your Roms subdirectory. Use the D-Pad or analogue stick to navigate to the desired rom, and press Cross or Start to select it. A new screen is displayed from which you can select to edit preferences for the rom or start emulation.

You can use the left and right shoulder buttons to cycle between other options screens in Daedalus.

Pause menu

When a rom is running, you can access the Pause Menu by pressing the 'Select' button.

From the Pause Menu you can use the left and right shoulder buttons to access various option screens. You can use the Pause Menu to take screenshots and reset the emulator to the main menu. Screenshots are saved under the Dumps/[gamename]/ScreenShots/ directory in the Daedalus folder on your Memory Stick.

You can press the 'Select' button again to quickly return to the emulator.

Controls

Start - Start

Analog - Analog

Circle+D-Pad - D-Pad

Cross - A button

Square - B button

Triangle - Z button

L/R - L/R

D-Pad - C buttons

As of R7 Daedalus now allows user-configurable controls to be specified. The desired controls can be chosen from the Rom Settings screen.

In order to define your own controller configuration you need to add a new .ini file to the Daedalus/ControllerConfigs directory. There are a few examples provided which should give an overview of what is possible.
