From the Launcher¶
The settings are arranged by subject, on different tabs:
To change a setting globally, so that it affects all games, select Options and then select the tab containing the setting you would like to change.
To change a setting for just one game, highlight the game in the games list, then select Edit Game and select the tab containing the setting you would like to change. To make the game use the settings on that tab instead of the global settings tab, tick Override global settings.
Not all settings are available for all games; for example, where there is no MIDI soundtrack for a game, there will be no MIDI or MT-32 tabs.
