Here's how to download eShop games from the home menu without putting your 3DS to sleep.
Tucked away in the version 9.0.0-20 update for the 3DS is a useful little trick that will enable players to download eShop games from the home menu without putting the 3DS to sleep.
Previously after selecting download later in the eShop, an ghosted icon would appear in the home menu and the download would begin once the 3DS was closed. Now, by double clicking the ghosted icon you can manually begin the download without having to relaunch the eShop.
