Tried default game properties-advanced;resolution size change, and unchecked "switch resolutions to fit" +defgameprops-display;unchecked "enforce aspect ratio"
...Still that game is fitted to screen, meaning I want righthandside of the screen out of the visible area at my monitor.
1b Is there a way to change game resolution for only one game, not going to default game properties when changes affect all games...
Any ideas? ...Other than playing with old dosmame

Previously at playchoice 10 games I did use option -320x240, and scrolled the screen with page up, At dosmame.
2. Maybe stupid question, but how do I check playback percentage with wolfmame?...after the playback...Other way than to only press f11 and see percentage during playback.
Thanks,
TJT
