Test Menu Info

As the majority (if not all) of G-Net boardsets are Japanese, the test menu can be a little confusing to those unfamiliar with the Japanese language!
The two most useful settings within the menu are: Screen Flip
Select the fifth option within the test menu, adjust the orange text so that it looks the same as the image below, then the one underneath, left option, bottom option from the main menu. Done.
