User guide

Compressed Disks

As of v0.10, 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.

Virtual keyboard

When the virtual keyboard is on, you can toggle the sticky keys feature (specifically for Shift and Ctrl). This allows Shift and Ctrl all to be held down at the same time while the user presses another virtual button.

Tap the Circle button and the selected virtual button remains held down and press again will release the virtual button.

Button configuration

By default, changes are not retained after button mapping is modified.

Please make sure to save (with Cross button) after desired mapping is configured.

Known issues

Fastloading - 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.
