Arcade machines are full of DIP switches and machine settings that allow arcades to tweak various aspects of the game. For example: game price and sound output. When Street Fighter 30th Anniversary Collection was first released, fans were happy to see that these machine settings could be toggled — then likely disappointed to find out some rather important settings available in the original machines were not there.
Well, it turns out those settings can still be switched, even if not through the game itself. With a little bravery (and the ability to edit XML files), you can still access those settings thanks to this run down from user “alb3530” on steam. You can check out the demonstration and instructions here.
