Reply To: How to add new emulator and make it default?

[herbfargus]

in the meantime if you want a script that sets up a script that will open up into unreal_speccy_portable then this does work (might cause some framebuffer issues potentially- make backups first) You’ll install it in place of the aforementioned script through the experimental menu of the setup script.
