I did say it was a guess - my N900 wasn't working at the time. It's actually a file: /home/user/.scummvmrc so (from X Terminal): Code: rm /home/user/.scummvmrc This will wipe out all settings for ScummVM. You can also try editing the file and deleting the setting for the specific game - the settings look fairly straightforward.
rm /home/user/.scummvmrc
