Version 0.9.0.26 (August 13 2008)

* A Spectrum joystick button/keyboard key can now be assigned to multiple PSP buttons
* Sticky key status will now be correctly reset when the virtual keyboard is toggled on/off

Installation

Unzip fuse.zip into /PSP/GAME/ folder on the memory stick.
Controls

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
[R] Show virtual keyboard
[L] + [R] 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).
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

Tape loading speed

Tape loading is excruciatingly slow, though this is more an issue with the emulated system, rather than the emulator. Fuse automatically turns off speed limiting (meaning, it runs as fast as it can) when tape loading is in effect, but on the PSP this doesn’t help a whole lot – approx. 50% boost at 222 MHz. Compare this to the Windows version, which speeds up to about 1500% to finish loading a game like Auf Wiedersehen Monty within seconds.
Compiling

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

svn co http://svn.akop.org/psp/tags/fuse/version

where version is the release version (for example, 0.9.0.1). Note that for this to work, you need to have Subversion installed.

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