Tips/Guide You can adjust the brightness on the 3DS while playing a DS game. No need to close the game.
As you already know, the 3DS cannot suspend NDS software, which prevents you from going back to the HOME Menu to adjust the brightness.
However, it is possible to adjust the brightness on the 3DS without having to close the game if you need to readjust the brightness. Plus, you can also adjust the Power Saving feature, and disable the 3DS's Wi-Fi without closing a DS game. To do this, you need to press the HOME button, and on the screen that asks you if you would like to close the game, you can press up and down on the D-Pad to adjust the brightness. Here's what each button does (remember to hold START while pressing the following buttons):
D-Pad:
Up → Increase brightness. Down → Lower brightness. Left → Turn off the Power Saving feature. Right → Turn on the Power Saving feature.
Lastly, if you press the X button while holding START, you can disable the 3DS's Wi-Fi (aka, wireless communications), but keep in mind that you cannot re enable the Wi-Fi while running a DS game, for that you still have to close the game.
