Ah, we have such clever members on our forum. thatoneguy159 has discovered that it’s possible to bypass the auto-loading feature on Nintendo 3DS demo units that force you to play Pilotwings Resort (and I imagine, any other game on display). This allows you to do pretty much everything on the 3DS.
Here are the steps he outlines:
1. Hold the power button until the 3DS is off.
2. Press and hold simultaneously the following buttons for 3 seconds: start, select, L, and R.
3. Press the power button and a menu should pop up on screen that asks about a StreetPass feature.
4. Press the home button to go to the menu.
He also points out that “Going to the system settings and exiting it will cause the game to auto-start again. Repeat the above steps to go back to the system menu. No other built in games do this.” There is a video from another user, lokilink, showing off this bypass in action, which you can see above.
