So i was wondering if you can make this app that you put these .3db (3dbook) files in a folder and the 3ds shows them. There could maybe even be a book maker/editor! The app would show a bookshelf. Then there would be a folder tab on the top left! You click that and it shows the root of the SD card folders! (This means you would put your books in a folder in the root of your SD card! Lets say i had a random book in a folder! The default folder to have is Books. I can see the random books cover on the bookshelf. I click on it and it shows the description. I can click back or read. I click read and see text. Once im done a page i click a arrow! You know what i saying. Anyways. To make these...i leave that up to you. Anyways, hope you like my idea!
