While doing a playthrough of Mega Madness on Duckstation I indeed ran into the problem where Romans in camps wouldn't move. I lowered overclocking speed to somewhere under 120%, but after that the game just stopped responding to my inputs besides Start (Enter). I changed it to 100%, still didn't respond to most inputs. I saved the game, restarted the emulator and loaded the save - still no response.
Everything started working again while I was typing this...
