New Features
Version 0.9.0.1 (July 09 2008)
- Initial release
Installation
Unzip fuse.zip into /PSP/GAME/ folder on the memory stick.
Controls
The emulator currently comes with the following default key mappings:
| Analog stick Up/Down/Left/Right | p/l/z/x |
| Directional pad Up/Down/Left/Right | 7/6/5/8 |
| [ ] (square) | Enter |
| O (circle) | Spacebar |
| [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.
Hangs during tape loading
The system randomly hangs when loading from tape – the longer the load time, the higher the possibility that it will hang. Hang may also occur when loading a state file that was saved while tape loading was in progress.
I’m not sure what’s causing the hangs, but to compensate for this, as well as the slow tape load speeds, Fuse PSP will load Z80 files, which are “save state” files from the Game menu.
Joystick support
Fuse PSP has joystick support, but my lack of familiarity with the system makes it difficult to test actual functionality. At this point, I’m not sure if joystick support in Fuse PSP works (I don’t think it does), but if you can help track this issue down, please contact me.
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://).
