Put the bios files in lowercase otherwise the emulator won't find them, and result in black screen.


By default, Quasi88 uses the keyboard for controls. To enable a controller:

Press F12.  This will bring up a menu with several tabs at the top.
Click the "mouse" tab.
Click the dropdown that's labelled "nomouse". Change it to "joystick".

Once this is done, the controls will be automatically mapped as such:

Left Joystick - Number Pad
A Button - Z key
B button - X key

Emulator: lr-quasi88

This emulator can be installed from the experimental menu of the RetroPie-Setup script.


lr-quasi88 utilises Retroarch configurations.

Add custom retroarch controls to the retroarch.cfg file in


For more information on custom RetroArch controls see: RetroArch Configuration
