I want to have an application to move firmware-done screenshots (L+down+select) into standard 3DS photo library.
The problem:
Not all games are supporting screenshot-making. In this situations we can use firmware button combination to make them. However, that screenshots placed in separate directory and do not shown in photos app. Even is you move the file, it still have to be renamed. Furthermore, it seems 3DS photos app have own stereoscopic files (firmware screenshots creates two separate jpegs instead - for left and right eyes). If there will be some problem with reverse engineering of stereo images, usual flat jpegs should be fine too.
Step 1. Just move all top photos for the left eye, rename the files appropriately
Step 2. As above, but with a stereoscopic files
Step 3. Own image viewer inside the app, more usable than photos app
Step 4. Option for clearing trash-screenshots in photos app directory, such as from Nintend-gs' streetpass
I'm working in IT industry since 2004. I know ASM A65 (NES), C/C++/C# etc. I think I can handle 3DS homebrew making too.
But I need the help with tutorials for 3DS homebrew making. I do not know anything about that.
Please, help me with links (not just "poke around devkitpro", but particular links to tutorials or something like that). Or, you can make such app yourself, inform me if you will, so I'll stop my searches.
