2.6.1 - startup_mode: default == no key input

[cfaehl]

AM works as expected on first run: autodetects emulator, builds romlist, brings up Attrac-man layout and that works as expected. On exiting and reloading with the generated and unedited config, no key input (perhaps no controller input, either) is accepted.

Changing attract.cfg startup_mode from "default" to "display_menu" works.
