lr-fuse
lr-fuse utilises Retroarch configurations
Add custom retroarch controls to the retroarch.cfg file in
/opt/retropie/configs/zxspectrum/retroarch.cfg
For more information on custom RetroArch controls see: RetroArch Configuration
By default,
- Buttons A, X and Y are mapped to the joystick's fire button, and button B is mapped to the UP directional button.
- Buttons L1 and R1 are mapped to RETURN and SPACE, respectively.
- The SELECT button brings up the embedded, on-screen keyboard.
If you are using more than one joystick, then it is worth reading the official documentation at lr-fuse Github page.
The default joystick emulated by lr-fuse is the Cursor joystick. If you wish to set Kempston as your default, then add the following line to the file /opt/retropie/configs/all/zxspectrum/retroarch.cfg
:
input_libretro_device_p1 = "513"
Running a 48K Machine
Some ZX Spectrum games require a 16K machine (e.g. Deathchase) or will run only on a 48K machine, for example, titles from Ultimate Play The Game such as Atic Atac and Jetpac.
By default, lr-fuse runs the 128K machine but it is possible to load the 48K machine on launch in the RetroArch Core options.
- Launch the game for which you wish to run on a 48K machine.
- The game will not load but launch the RGUI by pressing hotkey+X and navigate to
Quick menu
->Options
. - Set
Model (needs content load)
to48K
and then selectGame-options file
. This will save the setting to a game specific options file. - Exit lr-fuse and when you re-launch, the game should run.
Joypad to Keyboard Mapping
Thanks to forum member @pjft's contribution to lr-fuse, it is possible to play ZX Spectrum games without a need for a keyboard. This is useful for games that don't support joysticks such as Chuckie Egg and for games that require keyboard input in addition to a joystick (e.g. Head Over Heels).
- Launch a game you wish to map a joypad to a keyboard.
- Launch the RGUI by pressing hotkey+X and navigate to
Quick menu
->Options
. In the menu, assign a key to joypad buttonsJoypad Left mapping
,Joypad Right mapping
etc. as required. Below is an example for Chuckie Egg.
- Exit the RGUI and test in-game if necessary.
- To save, return to
Quick menu
->Options
in the RGUI and selectGame-options file
. This will save the mappings to a game specific options file.
