User guide

Tape and Disk Image Loading, Autoloading

Anytime you attempt to load a game from the Game tab, VICE PSP will reset the system; this is intended to make most games easily loadable.

To load tapes/disks without resetting the system, go to the System tab, select the Tape or Drive 8 menu option (depending on whether you want to load a tape or disk image) to load another image. If a tape or disk image is already loaded, it will be ejected, and another one will be loaded in its place.

To autoload a program (load a program from a mounted image directly), first load the image, then go to the System tab, highlight the Tape or Drive 8 menu option. Choose a program from the list and then select to autoload it. Note that autoloading will reset the system.

Save State Autoloading

VICE 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.

Screenshots

Known issues

Counter will sometimes report frames-per-second information incorrectly. This has to do with the sound rendering routine, which is shaky at the moment. Exiting to the emulator menu and returning will usually correct this.

When frame skipping is in effect, sound may crackle. This is also, most likely, a result of the above bug.
