New Features

Version (April 07 2009)


Unzip into /PSP/GAME/ folder on the memory stick.


The emulator currently comes with the following default key mappings:

Directional pad Up/Down/Left/Right Cursor keys (CAPS + 7/6/5/8)
Analog stick Up/Down/Left/Right Kempston joystick Up/Down/Left/Right
X (cross) Joystick Fire 1
[ ] (square) Enter
O (circle) Spacebar
Select 3
Start 0
® Show virtual keyboard
[L] +® Return to the emulator menu

When the virtual keyboard is on:

Directional pad select virtual button
[ ] (square) press a virtual button
O (circle) ‘stick’ a sticky virtual button
^ (triangle) unstick all stuck virtual buttons

Certain virtual buttons are “sticky” – the virtual button remains held down when O (circle) is tapped. Tapping O (circle) again releases the virtual button. To unstick all sticky buttons, press ^ (triangle).

Keyboard mappings can be modified for each game. Button configuration changes are not automatically retained after a mapping is modified. To save changes, press X (cross) after desired mapping is configured. To set the mapping as the default mapping, press [ ] (square).

Compressed Disks

As of version 0.10, Fuse PSP will load compressed disk (and TRD) images by extracting them to a temporary location, then opening the resulting file. This means that any changes made to a compressed disk will be lost if you either switch disks, or exit the emulator.

Save State Autoloading

Fuse PSP can be configured to automatically load a saved game whenever a new game is loaded via the Game tab. To do this, specify one of the save state slots as the Autoload slot (Options tab). If a saved game exists in the specified slot, it will be automatically loaded.

Known Issues


When fastloading is enabled, Fuse automatically turns off speed limiting when tape loading is in effect. This speeds up the loading process, but it may prevent certain TZX files from loading. If a TZX/TAP file does not load, try disabling fastloading.


Emulator’s source code is available via a Subversion (SVN) repository. To check out a particular version, run

svn co

where version is the release version (for example, Note that for this to work, you need to have Subversion installed.

To compile the emulator, you will need zlib (svn://) and libpng (svn://).
